XXII. Nuclear disintegrations caused by50–125 m e v protons: II

Summary A method of separating nuclear disintegrations caused in photographic emulsion by 50–125 mev protons into those in the light and those in the heavy nuclei of the emulsion is described. It is used to determine the characteristics of the disintegrations of the light and the heavy nuclei. These results show that about thirty per cent of the low energy particles emitted from nuclear disintegrations are the result of a nuclear cascade initiated by the primary particle.
