Matter radii of light proton-rich and neutron-rich nuclear isotopes

We extract the matter root-mean-square (rms) radii of a wide range of light proton and neutron rich nuclear isotopes (He-Mg) by studying their interaction cross sections (σI) on C12 at intermediate energies within the framework of the Glauber model. The calculations involve the nucleon densities obtained from harmonic-oscillator Slater determinants. The matter rms radii so obtained are compared with those available in the literature. It is demonstrated that the present description of matter densities can be conveniently used to explain the experimental values of σI, and the extracted matter rms radii may be considered an indication of the presence of halos and skins in proton- and neutron-rich nuclei.
