Phase-shift analysis of heavy-ion system near the Coulomb barrier

초록

A phase shift analysis of the elastic-scattering angular distributions for the 16O+ 63Cu system ranging from E <inf>lab</inf>=39 to 64 MeV is presented within the parametrized phase-shift model and the generalized Fresnel model. The observed data were well reproduced by the parametrized phase-shift model. The strong absorption radii exhibit a gradual decrease from 10.74 fm to 9.520 fm as the energy increases from 39 MeV to 64 MeV. The total reaction cross sections are also deduced at these energies.
