Abstract

The differential cross section for the excitation of the unbound 3+ (2.18 MeV) state in Li6 was measured by scattering a 227 MeV Ca40 beam from a Li6 target. Additionally, the cross section for the 3- (3.74 MeV) state in Ca40 was measured at the same center-of-mass energy by scattering a 34 MeV Li6 beam from Ca40. The cross section for excitation of the 3+, 2.18 MeV state in Li6 is 35 times larger than that of the Ca40 3- state. The present data and previously measured elastic scattering data have been analyzed in the framework of both distorted-wave Born approximation and coupled channels calculations, using double folded real potentials, to determine the influence of the inelastic states on the elastic scattering cross section. We find that the elastic scattering is very sensitive to coupled channels effects arising from the 3+ state in Li6.
