Effect of Woods-Saxon Potential on the 16O+20Ne Reaction Cross Section

The excitation function and angular distributions for the 16 O+20 Ne system have been explained using the distorted wave Born approximation (DWBA) calculations. The real and imaginary Woods-Saxon optical potentials are assumed to be energy-dependent. The gross resonant structures observed in the 20 Ne(16 O, 16 O)20 Ne excitation function are well described by the present DWBA calculations. Although the elastic and elastic-transfer analyses introduce a qualitative description of the experimental data, the coherent sum of the two reaction processes exhibit a much better result for both forward and large-angle data.
