Abstract
BOMBARDMENT of stressed single crystals of cadmium by alpha-particles was found by Andrade1 to cause a marked increase in the rate of glide under certain conditions. The crystals were stressed so as to produce a creep-rate of about 0.05 per cent per min., and increases in rate of up to five times were recorded on bringing up the alpha-particle sources during the early stages of the creep curve. The effect was attributed by Andrade to the initiation of new glide planes by the intense local disturbances produced in the surface of the crystal during the impact of the energetic alpha-particles.
