Fig. 1. (Color online) Angular distributions for the elastic scattering of 386 MeV
α-particles from
32S and
58Ni. The solid curves are the eikonal model calculations using tangential velocity whereas the dotted curves are the calculations using asymptotic velocity, where both results were calculated using the WS potential parameters given in
Table 1. The dashed curves are the calculation results that best fits the experimental data when using the asymptotic velocity, and the potential parameters used are shown in
Table 2. Experimental data are taken from Refs.
11,
12.
