The disintegration of boron by neutrons

Abstract

The tracks of the particles which result from the disintegration of boron by neutrons have been recorded by impregnating the emulsion of a photographic plate with borax. It is shown that there are two modes of disintegration, corresponding to the reactions: B10 + n1 → Li7 + He4, B10 + n1 → He4 + He4 + H3. Photomicrographs of the tracks, showing both modes of disintegration, are reproduced.
