The effect of nuclear matter compressibility on fusion cross-section and barrier distribution of deformed–spherical nuclei

Abstract

A method has been advised to calculate the interaction potential between deformed–spherical nuclear pair using density dependent nucleon–nucleon (NN) effective interaction. We performed our study on 16O– 238U nuclear pair using four types of recently derived density dependent NN forces. These forces correspond to different values of nuclear matter compressibility coefficient ( K). The orientation and density dependence on the heavy ion potential is studied at different nuclear matter compressibility. The fusion cross-section and the fusion barrier distribution have been calculated for the pair considered. We found that density dependence affects the fusion cross-section and the barrier distribution at low values of compressibility and no effect for high compressibility case.
