Elastic and Total Reaction Cross Sections of Oxygen Isotopes in Glauber Theory

We systematically calculate the total reaction cross sections of oxygen isotopes, O15-24 on a C-12 target at high energies using the Glauber theory. The oxygen isotopes are described with Slater determinants generated from a phenomenological mean-field potential. The agreement between theoretical and experimental results is generally good, but a sharp increase of the reaction cross sections from O-21 to O-23 remains unresolved. To examine the sensitivity of the diffraction pattern of elastic scattering to the nuclear surface, we study the differential elastic-scattering cross sections of proton-O-20.21.23 at the incident energy of 300 MeV by calculating the full Glauber amplitude.
