Inelastic scattering of heavy ions

Angular distributions and excitation functions for elastic and inelastic scattering have been measured with $sup 16$O, $sup 18$O, and $sup 32$S projectiles on Ca, Ni, Mo, and Sn isotopes. The experimental data show oscillations in the angular distributions which are more pronounced for projectile excitations than for target excitations. These oscillations are discussed within the semiclassical model. The experimental results have been analyzed with the modified distorted-wave Born-approximation (DWBA) code DWUCK. The theoretical predictions using conventional (marcroscopic form factor) DWBA calculations fail to describe the data accurately; a modification of the form factor is required to achieve a satisfactory description.
