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.

Supposing that in the primary and cascade gamma de-excitation processes of the compound nu- cleus, besides the giant dipole resonance model, there exist the deexcitation processes of the excited states of 6He, 6li,6Be, 7Li and 7Be particle Clusters, the γ-ray strength function in which these pro- cesses.
