EVIDENCE FOR "THERMAL SPIKES" IN THE ALPHA-PARTICLE RADIOLYSIS OF NITRATE CRYSTALS
Yields were determined for the decomposition of several alkali nitrate crystals by Po/sup 210/ alpha particles. These were compared with yields for decomposition by gamma and x rays and ultraviolet light at several temperatures. There is a pronounced effect of LET, and the effect of increasing LET ( gamma rays to alpha particles) roughly parallels that produced by increased temperature in the decomposition by radiations of low LET. It is suggested that, in addition to the high concentration of intermediates, the high temperature in heavy-particle tracks (thermal spikes) may also be an important factor in determining the track effect (LET effect).
