Microscopic description of recently measured reaction cross sections of neutron-rich nuclei in the vicinity of the N=20 and N=28 closed shells

• The reaction cross sections for neutron-rich nuclei with 7 <= Z <= 18 on a Si-28 target at intermediate energies (30-65A MeV) are calculated and are compared with the corresponding recently reported new measurements. A finite-range Glauber model along with a Coulomb modification is used. The required nucleon density distributions of the relevant projectiles and the targets are obtained in the relativistic mean field framework. The calculations reproduce the experiment well. A simple phenomenological modification of the zero-range Glauber model is proposed to incorporate the finite-range effects. This one-parameter expression is found to reproduce the experimental reaction cross sections quite well.
