Summary
The tracks of theα-particles from members of the thorium series have been recorded in a photographic emulsion, by the use of a technique previously developed. Radiothorium atoms introduced into the emulsion disintegratein situ, emitting fiveα-particles in succession. In this way “stars” are produced, consisting of five tracks radiating from a point, of which a discussion is given. Photomicrographs of two “stars” are reproduced.
