Preequilibrium model calculations of [gamma]-spectrum from3He+25Mg reaction at ELAB = 29.9 MeV

Abstract

High energy 7 -ray cross section obtained from 3He + 25Mg reaction at E\ab = 29.9 MeV exhibits an enhancement as compared to statistical model predictions including giant resonance strength functions. Within the preequilibrium exciton model approach which takes into account level density parameters and pairing for individual nuclei and uses the giant dipole resonance parameters found at lower excitation energy a satisfactory description of the 7-ray energy spectrum is obtained.
