Abstract. Nuclear interaction and charge-changing cross sections were measured for 950 · A MeV ²⁰N, ²⁰O, ²⁰F, ²⁰Ne, ²⁰Na and ²⁰Mg beams incident on a carbon target. The experimental results are compared to other data, in particular to those obtained for stable nuclei. Root mean square nuclear matter radii and upper limits of root mean square proton radii are derived from the experimental data. Evidence is presented for the existence of a neutron skin in ²⁰N.
