The interaction radii of proton-rich, radioactive 31Ga, 32Ge, 33As, 34Se, 35Br isotopes were measured using the direct method. The secondary beams were produced using a 78Kr primary beam of 73 MeV/nucleon in conjunction with SISSI and the SPEG spectrometers at GANIL. Most elements show reduced radii which vary with N, with a minimum around N = 36-38. The experimental reduced radii are compared to theoretical values obtained from Glauber reaction cross-section calculations based on Relativistic Mean Field (RMF) nuclear densities.
