Abstract

Unbound states in 17C were investigated via one-neutron removal from a 18C beam at an energy of 245 MeV/nucleon on a carbon target. The energy spectrum of 17C, above the single-neutron decay threshold, was reconstructed using invariant mass spectroscopy from the measured momenta of the 16C fragment and neutron, and was found to exhibit resonances at Er=0.52(2), 0.77(2), 1.36(1), 1.91(1), 2.22(3) and 3.20(1) MeV. The resonance at Er=0.77(2) MeV [Ex=1.51(3) MeV] was provisionally assigned as the second 5/2+ state. The two resonances at Er=1.91(1) and 3.20(1) MeV [Ex=2.65(2) and 3.94(2) MeV] were identified, through comparison of the energies, cross sections and momentum distributions with shell-model and eikonal reaction calculations, as p-shell hole states with spin-parities 1/2- and 3/2-, respectively. A detailed comparison was made with the results obtained using a range of shell-model interactions. The YSOX shell-model Hamiltonian, the cross-shell part of which is based on the monopole-based universal interaction, was found to provide a very good description of the present results and those for the neighbouring odd-A carbon isotopes - in particular for the negative parity cross-shell states., Comment: Physics Letters B 836 (2023) 137629, published

Abstract

The spectroscopic structure of 19C, a prominent one-neutron halo nucleus, has been studied with a 20C secondary beam at 290 MeV/nucleon and a carbon target. Neutron-unbound states populated by the one-neutron knockout reaction were investigated by means of the invariant mass method. The preliminary relative energy spectrum and parallel momentum distribution of the knockout residue, 19C*, were reconstructed from the measured four momenta of the 18C fragment, neutron, and beam. Three resonances were observed in the spectrum, which correspond to the states at Ex = 0.62(9), 1.42(10), and 2.89(10) MeV. The parallel momentum distributions for the 0.62-MeV and 2.89-MeV states suggest spin-parity assignments of 5/2+ and 1/2−, respectively. The 1.42-MeV state is in line with the reported 5/22+ state.

Abstract

A spectroscopic study of 17C was performed via the one-neutron knockout reaction of 18C on a carbon target at RIKEN-RIBF. Three unbound states at excitation energies of 2.66(2), 3.16(5), and 3.97(3) MeV (preliminary) were observed. The energies are compared with shell-model calculations and existing measurements to deduce their spin-parities. From the comparison, the states at 2.66(2) and 3.97(3) MeV are suggested to be 1/2− and 3/2−, respectively. From its decay property, the state at 3.16(5) MeV is indicated to be 9/2+.

Abstract

Within the SEASTAR project at RIKEN-RIBF, 66Cr and 70,72Fe have been produced via protonknockout reactions, and their first excited 2+ and 4+ states have been discovered. The combination of the liquid-hydrogen target and TPC system MINOS has been used in combination with the DALI2 detector array for the first time. A 345 MeV/u 238U beam with a mean intensity of about 12 pnA impinged on a Be target. Fission fragments were separated and identified using the BigRIPS spectrograph, and reaction products were analyzed using the ZeroDegree spectrograph. A plateau of excitation energies, with a small change in the systematic trends past N = 44, reveals an extension of the N = 40 region of collectivity toward N = 50. Hence, the isotopes of interest are located within the N = 40 island of inversion. An interpretation of the observed trends is offered through large scale shell model calculations.

Abstract

Two astrophysically important reactions, 22Mg(p,γ)23Al and 26Si(p,γ)27P, were studied experimentally by using the Coulomb dissociation of proton-rich nuclei 23Al and 27P. The radiative widths determined from the cross sections suggest that the β+ decay of 22Mg is favored over the 22Mg(p,γ)23Al reaction while 26Si(p,γ)27P reaction is faster than the β+ decay of 26Si around the peak temperature of heavy novae. The measured radiative widths are consistent with the theoretical values used in the network calculations of nucleosynthesis, therefore providing confirmation that the theoretical stories of nucleosynthesis do not require any change in these sites of the reaction chains.

Abstract

Coulomb dissociation of loosely bound nuclei 11Be and 15C have been studied in a kinematically complete measurement. For 11Be, the n-10Be relative energy spectrum has been analyzed as a function of the impact parameter, b. The obtained spectrum with b ≥30 fm agrees very well with the first order perturbation theory assuming a pure Coulomb process. It suggests that a selection of the impact parameter is effective to exclude the higher order effect and the nuclear breakup contribution from the measured dissociation cross section. The spectroscopic factor for 10Be(0+) ⊗1s1/2 in the ground state is then extracted to be 0.69(3). The result of 15C has been applied to determine the 14C(n,γ)15C cross section, which is relevant to the stellar nuclear synthesis such as the CNO cycle in low mass AGB stars. The obtained neutron capture cross section is consistent with that of the p-wave direct capture process.

Abstract

We have measured Coulomb excitation of 24Si to its first excited state to obtain the E2 transition probability. This is the first measurement of B(E2) for a TZ = −2 nucleus, which enables us to compare their transition probabilities between the mirror pair of T = 2, namely 24Si and 24Ne.

Abstract

The g-factor for the 17C ground state was measured by means of the β-NMR spectroscopy with a spin-polarized fragment beam. From the tentative result |g (17C)| = 0.5054(25), we conclude that the ground-state spin-parity for 17C is 3/2+.
