Abstract：
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.Two reaction mechanisms are considered.They are compound nucleus statistical process and two nonstatistical process,i.e.,radiative capture in compound elastic scattering channels and direct semidirect radiative capture in shape elastic scattering channels.Incident energy of neutron is chosen in the region of 0.1-20MeV.The calculated results are given and compared with the experimental values for ²⁷Al,^{40^{Ca,⁶³Cu and ⁹³Nb.The variational pattern is analyzed and discussed.}}
