Strongly Oscillating Angular Distributions in the ReactionS32(O16,C12)Ar36atEc.m.=30MeV

Abstract
The elastic scattering of O16 on S32 and the reaction S32(O16, C12)Ar36 have been measured at Ec.m.=30 MeV. The elastic-scattering angular distribution exhibits a smooth Fresnel-type diffraction pattern, whereas for the (O16, C12) reaction we observe strong oscillations in the ground- state transition.
