Abstract

Heavy-ion transfer reactions are studied using the exact finite-range DWBA (distorted wave Born approximation) calculations. To investigate the differential cross sections in the whole-angle region the reaction mechanism is considered as a coherent sum of direct and exchange processes. Both the double-folding microscopic nucleon–nucleon interaction and phenomenological Woods–Saxon form are used for the real and imaginary distorting potentials in the initial and final channels, respectively. The present calculations are in good agreement with the experimental data in the whole angular range. The inclusion of the exchange process improves the cross section's magnitude explicitly and leads to a better description of the backward oscillations. The values of the extracted normalization coefficients obtained are reasonable.
