Abstract

We have measured the interaction cross sections (σ_I) of ^31-40 Ar and ^31-37C1 on carbon targets at energies of around 950 A MeV. The effective matter radii for these nuclei were deduced by a Glauber-model analysis. Combining our matter radii with measured charge radii for Ar isotopes, we could deduce the proton-skin thicknesses for the ^32-40 Ar isotopes, which were found to increase monotonically with decreasing neutron number. The larger radius of the proton drip-line nucleus ³¹ Ar suggests an anomalous structure for this nucleus. In addition, using NaI(T1) arrays surrounding the carbon target, we measured γ-rays emitted from excited states in these isotopes. In this way we could deduce the upper limits for the inelastic cross sections (σ_inela) on carbon targets at energies of around 950 A MeV.

N2 - We have measured the interaction cross sections (σI) of 31-40 Ar and 31-37C1 on carbon targets at energies of around 950 A MeV. The effective matter radii for these nuclei were deduced by a Glauber-model analysis. Combining our matter radii with measured charge radii for Ar isotopes, we could deduce the proton-skin thicknesses for the 32-40 Ar isotopes, which were found to increase monotonically with decreasing neutron number. The larger radius of the proton drip-line nucleus 31 Ar suggests an anomalous structure for this nucleus. In addition, using NaI(T1) arrays surrounding the carbon target, we measured γ-rays emitted from excited states in these isotopes. In this way we could deduce the upper limits for the inelastic cross sections (σinela) on carbon targets at energies of around 950 A MeV.
