Neutron capture cross section
-
The W isotopic compositions have been investigated within the classical approach to the sprocess nucleosynthesis. The Maxwellian averaged neutron capture cross-sections (MACS) adopted in the calculation are obtained from the TALYS-1.9 code with four nuclear level density models: the constant temperature plus Fermi gas, the back-shifted Fermi gas, the generalised superfluid, and the microscopic method of Goriely.

These filtered neutron beams have been applied efficiently for experimental researches on neutron total and capture cross sections measurements, and elemental analysis in various kinds of samples based on the prompt gamma neutron activation analysis method. This paper reviews the progress of filtered neutron beams development and its applications for past many years at the Dalat nuclear research reactor.

In the current paper, we investigate the application of the Equivalent Generalized Perturbation Theory (EGPT) to derive trends and associated covariances on the neutron capture cross section of one major fission product for both light water reactors and sodium-cooled fast reactors which is Rhodium-103.

In order to improve the accuracy of the experimental results the effect of the non-ideal epithermal spectrum was taken in to account by determining the neutron spectrum shape factor (α), and the corrections for the thermal (Gth) and the resonance (Gepi) neutron self-shielding effects, the γ-ray attenuation (Fg) and the γ-ray coincidence summing effect were made. The thermal neutron cross-section for the 45Sc(n,γ) 46Sc reaction has been determined to be σo = 27.6 ± 0.8 barn.
