Matter radii of [superscript 32–35]Mg

Abstract

The interaction cross sections of [superscript 32–35]Mg at 900A MeV have been measured using the fragment separator at GSI. The deviation from the r[subscript 0]A[superscript 1/3] trend is slightly larger for [superscript 35]Mg, signaling the possible formation of a longer tail in the neutron distribution for [superscript 35]Mg. The radii extracted from a Glauber model analysis with Fermi densities are consistent with models predicting the development of neutron skins.
