Abstract

12C +12 C is the main reaction during core and shell carbon burning in massive stars, however, at temperatures higher than 109K when most of the carbon is depleted and its abundance is lower than 16O, the 12C +16 O fusion can also become relevant. Moreover, 12C +16 O reaction can ignite also in the scenario of explosive carbon burning. The astrophysical energy region of interest thus ranges from 3 to 7.2 MeV in the center-of-mass frame. There are various measurements of the cross-section available in the literature, however, they all stop around 4 MeV, making extrapolation necessary at lower energies. To try to solve this uncertainty and corroborate direct measurement the Trojan Horse Method was applied to three-body processes 16O(14N, α24Mg)2H and 16O(14N, p27Al)2H to study the 16O(12C, α)24Mg and 16O(12C, p)27Al reactions.

Abstract

The carbon-burning process in massive stars mainly occurs via the 12C +12 C. However, at temperatures higher than 109K and considering the increased abundance of 16O produced during the later stages of the heliumburning,the 12C+16O fusion can also become relevant. Moreover, 12C+16O also plays a role in the scenario of explosive carbon burning. Thus, the astrophysical energy region of interest ranges from 3 to 7.2 MeV in the center-of-mass frame. However, the various measurements of the cross-section available in the literature stop around 4 MeV, making extrapolation necessary. To solve this uncertainty and corroborate direct measurement we applied the Trojan Horse Method to three-body processes 16O(14N, α24Mg)2H and 16O(14N, p27Al)2H to study the 12C(16O, α)24Mg and 12C(16O, p)27Al reactions in their entire energy region of astrophysical interest. In this contribution, after briefly describing the method used, the experiment and the preliminary phases of the data analysis will be presented and discussed.

Abstract

The nuclear structure of $^{66}$Se, nucleus beyond the N=Z line on the proton-rich side of the valley of stability, was investigated by the neutron knock-out reaction $^{67}$Se($^{12}$C,X)$^{66}$Se using a $^{12}$C target. The analysis of the singles spectrum of the γ-rays emitted during the de-excitation of the populated low-lying excited states revealed two previously detected (927(4) keV, 1460(32) keV) and three new (744(6) keV, 1210(17) keV, 1661(23) keV) transitions. The 744-keV, the 1210-keV, and the 1460-keV transitions were found to be in coincidence with the one at 927 keV. The spectrum coincident with the 927-keV transition showed a further possible transition at 299(35) keV, which was obscured by significant atomic background in the singles spectrum. This transition might correspond to a peak previously reported at 273(5) keV that could not be assigned to $^{66}$Se unambiguously. Based on a comparison of the experimental data to theoretical calculations, four new excited states are proposed which suggest that $^{66}$Se exhibits shape coexistence.

Abstract

The 12C + 16O fusion reaction plays a role in the later stages of carbon burning, influencing the evolution of both massive stars and Type Ia Supernovae: when most of the carbon is depleted, by the main fusion reaction 12C + 12C, the abundance of 16O nuclei is significantly higher. Therefore 12C + 16O can indeed have a strong impact on the process. In this brief contribution, preliminary data analysis results of a new indirect measurement of the 12C + 16O, performed at astrophysical energies via the Trojan Horse Method, will be presented and discussed.

Abstract

We attempted to determine the astrophysical S-factor of the direct part of the 18O(p, γ)19F capture by the indirect method of asymptotic normalization coefficients (ANC). We measured the differential cross section of the transfer reaction 18O(3He, d)19F at a 3He energy of 24.6 MeV. The measurement was realized on the cyclotron of the NPI in Řež, Czech Republic, with the gas target consisting of the high purity 18O (99.9 %). The reaction products were measured by eight ∆E-E telescopes composed from thin and thick silicon surface-barrier detectors. The parameters of the optical model for the input channel were deduced by means of the code ECIS and the analysis of transfer reactions to 12 levels of the 19F nucleus up to 8.014 MeV was made by the code FRESCO. The deduced ANCs were then used to specify the direct contribution to the 18O(p, γ)19F capture process and were compared with the mutually different results of two works.

Abstract

Gamma ray astronomy has made big strides in the last decades paving the way to a better understanding of explosive nucleosynthesis. In particular, crucial information on novae nucleosynthesis is linked to the abundance of the 18F isotope, which might be detected in explosive environments. Therefore, the reaction network producing and destroying this radioactive isotope has been extensively studied in the last years. Among those reactions, the 18F(p,α)15O cross section has been measured by means of several dedicated experiments, both using direct and indirect methods. The presence of resonances in the energy region of astrophysical interest has been reported by many authors. In the present work a report on a recent experiment performed via the Trojan Horse Method (THM) at the Texas A&M Cyclotron Institute is presented and the results are given and compared with the ones known in the literature, both direct and indirect. Data arising from THM measurements are then averaged and the reaction rate calculated in the novae energy range. Hints on future astrophysical applications will also be given.

Abstract

In the recent work at Notre Dame, correlations between three carbon isotope fusion systems have been studied and it is found that the fusion cross sections of 12C+13Cand 13C+13C provide an upper limit on the fusion cross section of the astrophysically important 12C+12C reaction.The aim of this work is to continue such research by measuring the fusion cross section of the 12C+13C reaction to lower energies. In this experiment, the off-line activity measurement was performed in the ultra-low background laboratory 12C+13C and the fusion cross section for has been determined in the energy range of Ec.m. =2.5–6.8 MeV. Comparison between this work and several models is also presented.

Abstract

International audience; We discuss the elastic scattering 4He + 24Mg at 50 MeV as a good example of a whole range of phenomena that compete in heavy ion reactions and can be identified in elastic scattering data. The reaction is dominated by deep optical potentials and shows all characteristics of a strongly refractive scattering: Fraunhofer diffractive oscillations at very forward angles, shallow Airy oscillation forward to a rainbow bump, significant increase of the cross section at large angles. Primitive evaluation of the deflection function indicates a strong orbiting singularity. The lowest order eikonal expansion of the scattering phase suggests a typical rainbow pattern, though the rainbow angle lies far beyond the physical angular range. The semiclassical uniform multireflection expansion of the scattering amplitude tells that the strong refractive effects associated with orbiting are carried by the internal barrier component which retains contributions from trajectories refracted by the spherical well. A complementary analysis in terms of unitary Regge pole amplitudes shows that the effects associated with the break in the exponential decay of the rainbow tail could be interpreted as simple diffraction due to pole(s) in the S-matrix. This strengthen the conjecture that orbiting and Regge poles are dual aspects of heavy ion scattering. The similarity with the Fresnel clothoide for light diffraction is exemplified with a schematic model that allows an almost exact calculation of the scattering amplitude.

Abstract

ONe novae thermonuclear simulations still show uncertainties in the abundance of the final elements. This comes from the uncertainties that are present in some reaction rates that are considered to be important. One of this is the resonant proton capture on 30P. For decades various experiments tried to restrain the large variations in the reaction rates and many improvements have been made, but the results are still inconclusive. Decay spectroscopy This proceeding paper aims to make a comparison between two indirect methods that can be used to reach the reaction rate of the above-mentioned reaction, by briefly describing the procedure and detection methods used.

47. Study of the 9C Breakup Through NP1412-SAMURAI29R1 Experiment.

Abstract

The 9C breakup reaction was investigated in order to obtain information about the inverse reaction: 8B(p,γ)9C at astro-physical energies within the NP1412SAMURAI29R1 experiment. The 8B(p,γ)9C reaction gives a possible path to the hot pp chain pp-IV at high temperatures and away from it toward a rapid alpha-process rap-I at high temperatures and densities and therefore is important in understanding nucleosynthesis in super-massive hot stars in the early universe, including possible bypass of the 3α-process. For this experiment it was proposed to use a combination of nuclear and Coulomb dissociation measurements (on a light target Be or C and on a heavy target Pb, respectively) at energy of 160 A MeV to extract structure information, which will allow to evaluate the radiative proton capture cross section at low energies and from there the reaction rate. The current work is focused on the development of Monte Carlo simulations for Coulomb breakup mechanism of 9C as well as on the Geant4 simulations of the resulting particle trajectories through the experimental setup, including passage of the particles through the magnetic field of the SAMURAI spectrometer.

Abstract

Using our IFIN-HH facilities: the 3 MV TandetronTM accelerator and the ultra-low background laboratory we were able to study the 4He+64Zn reaction at energies under Coulomb barrier. With these facilities, cross sections of the order of 30 nb were obtained. The thick target yields were determined through measurements of γ-ray yield followed by the decay of 67Ga (T1/2=78.28 h) in two laboratories: microBequerel (the ultra-low background laboratory) and NAG (Nuclear Astrophysics Group) where the gamma rays were detected with HPGe detectors with a relative efficiency of 120% and 100% respectively. In addition, prompt in-beam gamma-rays were detected with an HPGe detector in close proximity as long as the reaction cross section was sufficiently large for those gammas to be extracted from the target hall background. Results of the experiment are shown below. [ABSTRACT FROM AUTHOR]

Abstract

The 12C(12C,α0,1)20Ne and 12C(12C,p0,1)23Na reactions have been measured from Ec.m.=2.7 MeV down to 0.8 MeV via the Trojan Horse Method o the deuteron in 14N. This range of energies is relevant in astrophysical scenarios, from superburst ignition to explosive stellar carbon burning. The deduced astrophysical S(E) factors exhibit several resonances that are responsible for a very large increase of the reaction rate at the relevant temperatures. [ABSTRACT FROM AUTHOR]
