Abstract

We report the measurement of a neutron radiative cross section on a target with a high gamma activity, at the Los Alamos DANCE detector (Detector for Advanced Neutron Capture Experiments) for the first time. The (n, γ) reaction properties of the unstable 173Lu isotope were studied. Two experimental campaigns were needed to determine the 173Lu(n, γ) cross section. They were performed at the Los Alamos Neutron Science Center (LANSCE) spallation neutron source facility. To this end, two targets were produced from an Hf sample using successively proton irradiation and chemical separations. They were composed of 173Lu, 174Lu, and 175Lu isotopes. The two measurements were conducted at two-year intervals, taking advantage of the difference of the isotopic decay lifetimes in order to identify resonances from the 173Lu(n, γ) and 174Lu (n, γ) reactions. Just over one hundred new resonances were observed, the majority of which come from the 173Lu(n, γ) reaction. Only a few of them were assigned to the 174Lu (n, γ) reaction. As regards the 173Lu(n, γ) reaction, the radiative neutron capture cross section was determined over the energy range from thermal neutron up to 200 eV. The parameters of resonances in the resolved resonance region were extracted with the sammy code while calculations with talys determined the capture cross section in the unresolved resonances region. At the keV region, we performed standard talys calculations as well as other microscopic investigations by substituting the standard talys photon strength function by another one from QRPA models.

15. Radiative neutron capture cross section from 236U.

Abstract

The 236U(n,γ) reaction cross section has been measured for the incident neutron energy range from 10 eV to 800 keV by using the Detector for Advanced Neutron Capture Experiments (DANCE) γ-ray calorimeter at the Los Alamos Neutron Science Center. The cross section was determined with the ratio method, which is a technique that uses the 235U(n,f) reaction as a reference. The results of the experiment are reported in the resolved and unresolved resonance energy regions. Individual neutron resonance parameters were obtained below 1 keV incident energy by using the R -matrix code sammy. The cross section in the unresolved resonance region is determined with improved experimental uncertainty. It agrees with both ENDF/B-VII.1 and JEFF-3.2 nuclear data libraries. The results above 10 keV agree better with the JEFF-3.2 library. [ABSTRACT FROM AUTHOR]

16. Isomeric ratio measurements for the radiative neutron capture 176Lu(n,γ) at the LANL DANCE facility.

Abstract

The isomeric ratios for the neutron capture reaction 176Lu(n,γ) to the Jp=5/2-, 761.7 keV, T1/2=32.8 ns and the Jp=15/2+, 1356.9 keV, T1/2=11.1 ns levels of Lu177 have been measured for the first time. The experiment was carried out with the Detector for Advanced Neutron Capture Experiments (DANCE) at the Los Alamos National Laboratory. Measured isomeric ratios are compared with talys calculations using different models for photon strength functions, level densities, and optical potentials. In order to reproduce the experimental γ-ray spectra, a low-energy resonance must be added in the photon strength function used in our Hauser-Feshbach calculations. [ABSTRACT FROM AUTHOR]

Abstract

The cross section of the neutron capture reaction 176Lu(n,γ) has been measured for a wide incident neutron energy range with the Detector for Advanced Neutron Capture Experiments at the Los Alamos Neutron Science Center. The thermal neutron capture cross section was determined to be (1912±132) b for one of the Lu natural isotopes, 176Lu. The resonance part was measured and compared to the Mughabghab's atlas using the R-matrix code, sammy. At higher neutron energies the measured cross sections are compared to ENDF/B-VII.1, JEFF-3.2, and BRC evaluated nuclear data. The Maxwellian averaged cross sections in a stellar plasma for thermal energies between 5 keV and 100 keV were extracted using these data. [ABSTRACT FROM AUTHOR]
