Abstract

Proton-rich isotopes of Ga, Ge, As, Se and Br had their total reaction cross-sections (σ_R) measured. Root-mean-squared matter radii were determined from Glauber model calculations, which reproduced the experimental σ_R, values. For all isotopic series a decrease of the r_rms with increasing neutron number and a correlation with deformation was observed.
