Abstract
SEVERAL workers have investigated the radioactivity of samarium, and it is established that this element emits short-range-particles. Mäder1 has also reported the existence of a group of particles of range 1.37 cm., which he believes to be protons. To obtain fuller information about these particles, I have introduced samarium sulphate into the emulsion of an Ilford R plate, and examined the tracks which are produced. The technique of this method has been previously described2.
