Relativistic mean field for nuclear periphery Original Research Article

The Relativistic Mean Field (RMF) formulation is used to describe the nuclear periphery, the central theme in the study of the unstable nuclei. First, we analyze the available antiproton annihilation experimental data in terms of the extracted peripheral factors representing the ratio of neutron to proton densities at about 2.5 fm away from the half density radius of the target nucleus. Next, we calculate in the Glauber model, the reaction cross sections for A = 20 isobars as projectiles on 12C target using the RMF densities as input and compare with the corresponding measured cross sections. The theory (RMF) accounts well the experiment in both the cases.
