Phase-shift analysis and first-order Eikonal correction to optical potential by inversion for 16O+28Si elastic scattering at Elab = 1503 MeV

초록

We analyze 16O+28Si elastic scattering at E<inf>lab</inf> = 1503 MeV using a phase shift analysis based on McIntyre parametrization of S-matrix. The near- and far-side decompositions of elastic cross section have been also performed by following Fuller's formalism. By using the inversion procedure of McIntyre S-matrix, the optical potential is obtained and its result was compared with one of the optical model analysis. The first-order eikonal correction effect on the optical potential by inversion is discussed.
