Abstract
Specimens of gallium antimonide were irradiated at liquid nitrogen temperature with 12-Mev deuterons. The results of resistivity measurements during irradiation and of x-ray observations after the irradiation suggest very strongly that thermal spikes are introduced under these conditions. In particular from the shape and the intensity of the x-ray reflections the conclusion is drawn, that in these spike regions the material is present in a liquid-like lattice configuration, markedly different from the matrix configuration. The observations on annealing support the suggested model.
