Abstract

High-energy interaction cross sections of A = 20 nuclei (²⁰N, ²⁰O, ²⁰F, ²⁰Ne, ²⁰Na, ²⁰Mg) on carbon were measured with accuracies of ≈ 1%. The nuclear matter r.m.s. radii derived from the measured cross sections show an irregular dependence on isospin projection. The largest difference in radii, which amounts to approximately 0.2 fm, has been obtained for the mirror nuclei ²⁰O and ²⁰Mg. The influence of nuclear deformation and binding energy on the radii is discussed. By evaluating the difference in r.m.s. radii of neutron and proton distributions, evidence has been found for the existence of a proton skin for ²⁰Mg and of a neutron skin for ²⁰N.
