Recently the inverse mean field method (Imefim) has been shown to lead to a specific energy dependence of the real central nuclear part, V, of the optical model potential for nucleon-nucleus scattering. Proceeding from V towards the imaginary volume term of the potential, Wυ, application of conservation laws yields a specific energy dependence for Wυ. It compares favourably with heuristic potentials.

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.

In this paper, the quasi-elastic scattering (p, n) reactions are studied for a wide range of target nuclei 13C, 14C, 48Ca, 90Zr and 208Pb and different incident energies (35-160 MeV). The phenomenological Optical model potential and density independent approaches are used for these calculations in comparison with density dependent semi-microscopic approach. The density dependent parameters are modified to achieve the best calculations for many targets at different energy levels.
