Abstract

A theoretical study of the influence of configuration mixing on elastic scattering cross section is performed for the system ¹⁶O + ²⁷Al at 100 MeV. A simple twostate model space, including the ²⁷Al 5/2⁺ ground and 5/2⁺ excited state at 2.73 MeV, is used in the coupled channel equations. The results indicate that even a weak degree of mixing is able to sizeably affect the elastic cross section, determining mainly a damping of Fraunhofer oscillations, as observed in the experiments.
