Contributions of density-dependent interactions in heavy-ion transfer reactions

Abstract

Heavy-ion reactions with particle transfer are studied using the distorted-wave Born-approximation formalism. Different forms of the distorting optical model potentials are introduced in the initial and final channels. The form factors of the reactions are presented explicitly using modified real Woods–Saxon potentials for the nucleus–nucleus bound-state interactions in the entrance and exit channels. The differential cross sections of heavy-ion transfer reations are calculated numerically using the double-folding model for distorting potentials with an effective density-dependent nucleon–nucleon interaction. The present analyses of the angular distributions introduce good descriptions of the experimental data. The observed backward oscillations are described successfully by the explicit inclusion of the density- and the parity-dependent terms in the distorting optical-model potential calculations. The values of the extracted spectroscopic factors and normalization coefficients obtained are reasonable.
