Abstract

IN a letter published in NATURE of July 15, 1939, p. 115, attention was directed to the fact that the photographic plate provides a very powerful instrument for investigations depending on the detection and measurement of the energy of heavy charged particles, notably protons, and of neutrons. It was shown that the method, when applied to determining the energies of the neutrons liberated from the light elements under deuteron bombardment, yields essentially the same information as that provided by the expansion chamber. The photographic method has, however, marked advantages over the expansion chamber, which were described.
