Study of (n, 2n) reaction cross sections for 107Ag within the energy range of 9–22 MeV

Popis výsledku v původním jazyce

The 107Ag(n, 2n)106mAg reaction cross sections at the neutron energies of 10.50 ± 0.68, 13.52 ± 0.67, 16.86 ± 0.58 and 19.86 ± 0.59 MeV were measured by using the off-line γ-ray spectroscopy and activation analysis techniques. The 7Li(p, n) reaction was used to produce the high-energy quasi-monoenergetic neutrons with the proton beam from the 14UD BARC-TIFR Pelletron facilities at Mumbai, India. The neutron flux was monitored using the standard 27Al(n, α)24Na monitor reaction. The detailed uncertainties analysis in the measured cross sections was performed using the covariance analysis. The cross sections were also theoretically calculated using TALYS-1.9 code from 10 to 25 MeV energies. The measured cross-sections data are compared with the evaluated data from TENDL-2019, JENDL-4.0 and ENDF/B-VIII.0 libraries as well as with the existing experimental data available in EXFOR compilation. Our data show good agreement with some of the previous experimental data and with the theoretical values calculated with TALYS-1.9 code. Present work will provide better description of level density models and pre-equilibrium process.
