An Unified Formalism to Study Nonstatistical Effects in Radiative Vapture Reactions

  • Based upon an consistent description of the wave function of the captured state and the final state,an unified formalism was established to investigate the nonstatistical effects in radiative nucleon capture reactions at energies ranging from 0.1 to 20MeV.This model includes the direct-semidiect capture and the radiative capture in the compound elastic and inelastic channels.By applying this model theory and including also the statistical contributions of the compound nucleus process,the radiative neutron capture cross sections in 27Al,55Mn,89Y and 208Pb are calculated and the results are compared with the measured data.

Abstract: Based upon an consistent description of the wave function of the captured state and the final state,an unified formalism was established to investigate the nonstatistical effects in radiative nucleon capture reactions at energies ranging from 0.1 to 20MeV.This model includes the direct-semidiect capture and the radiative capture in the compound elastic and inelastic channels.By applying this model theory and including also the statistical contributions of the compound nucleus process,the radiative neutron capture cross sections in 27Al,55Mn,89Y and 208Pb are calculated and the results are compared with the measured data.
