Elastic and inelastic scattering of 240-MeV (6)Li ions from (40)Ca and (48)Ca and tests of a systematic optical potential

Abstract

Elastic and inelastic scattering of 240-MeV (6)Li particles from (40)Ca and (48)Ca were measured with the multipole-dipole-multipole spectrometer from 4 degrees <= theta(c.m.) <= 40 degrees. Optical potential parameters were obtained by fitting the elastic-scattering data with the double-folding model using the density-dependent M3Y NN effective interaction and B(E2) and B(E3) values obtained for low-lying 2(+) and 3(-) states agreed with the adopted values. The results are compared with those obtained using potentials derived from the systematics of potentials previously obtained for (24)Mg, (28)Si, (58)Ni, and (90)Zr. Cross sections for excitation of giant resonances were also calculated with the potentials obtained.
