Optical potentials by inversion for 16O ion elastic scatterings at Elab = 1503 MeV

초록

The optical potentials by inversion are presented in two ways. The first one is to use the inverse eikonal relations derived from McIntyre phase shifts. The second one is to solve the inversion problem based on McIntyre parametrization of S-matrix corresponding to the Woods-Saxon type optical potentials. The optical potentials obtained from the two inversion methods are applied to the systems 16O+12C, 16O+28Si, and 16O+40Ca at E<inf>1ab</inf> = 1503 MeV. The calculated results are compared with those from the optical model analysis. It is shown that both the two methods lead to reasonable agreements, in the surface region, to the results from the optical model analysis.
