Study on Photon Transmission Coefficient and Capture Cross Section of Isomeric State

  • The formulas for calculating the photon transmission coefficient and the capture cross section of the isomeric state for the compound nucleus reaction are presented,in which statistical and non-statistical processes are all contained.Calculating the photon transmission coefficient by solving the cascade deexcitation processes,the (n,γn)processes are deducted reasonably,and the contribution of the first transitions to the levels distributed above the neutron separating energy Bn can be included.The numerical calculations for 59Co and 103Rh in the energy below 4MeV are made.The different calculation methods for the photon transmission coefficients are compared with other and the calculation results of the isomeric capture cross sections are compared with the experimental data.Analysis and discusions,especially the dependence of calculated results on energy level distributions are presented.

Abstract: The formulas for calculating the photon transmission coefficient and the capture cross section of the isomeric state for the compound nucleus reaction are presented,in which statistical and non-statistical processes are all contained.Calculating the photon transmission coefficient by solving the cascade deexcitation processes,the (n,γn)processes are deducted reasonably,and the contribution of the first transitions to the levels distributed above the neutron separating energy Bn can be included.The numerical calculations for 59Co and 103Rh in the energy below 4MeV are made.The different calculation methods for the photon transmission coefficients are compared with other and the calculation results of the isomeric capture cross sections are compared with the experimental data.Analysis and discusions,especially the dependence of calculated results on energy level distributions are presented.
