A theoretical study of the influence of configuration mixing on elastic scattering cross section is performed for the system O-16 + Al-27 at 100 MeV. A simple two-state model space, including the Al-27 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.

Abstract
A theoretical study of the influence of configuration mixing on elastic scattering cross section is performed for the system O-16 + Al-27 at 100 MeV. A simple two-state model space, including the Al-27 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.File in questo prodotto:
