Abstract
The bombardment of lithium by deuterons has been shown by Crane, Delsasso, Fowler and Lauritsen (1935) and by Rumbaugh and Hafstad (1936) to lead to the formation of a radioactive product which emits
β
-rays and has a half life of 0·88 sec. Recently, Lewis, Burcham and Chang (1937) showed that this emission of
β
-rays is accompanied by ∝-particle emission which decays with the same period. These two disintegrations may be explained by the following chain of reactions in which the radioactive

Li nucleus with a half life of 0·88 sec. disintegrates into two ∝-particles and an electron and neutrino:
