摘要：
Elastic and inelastic scattering of 240-MeV Li-6 particles from Ca-40 and Ca-48 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 Mg-24, Si-28, Ni-58, and Zr-90. Cross sections for excitation of giant resonances were also calculated with the potentials obtained.
