neutron radiative capture

Using the hypothesis as well as the γ-ray strength function proposed by us, the neutron radiative capture reaction cross sections and the γ energy spectra have been calculated for 93Nb,natural Ag and 181Ta in the neutron incident energy region from 0 01 to 5MeV as well as for 197Au in the neutron incident energy region from 0 01 to 10MeV.

The mass number dependence and the neutron incident energy dependence of the radiative capture cross sections from various reaction mechanisms of the neutron radiative capture process have been examined in the nuclear mass region A <100.
