A mechanism for neutron emission from deuterated metals is described, based on a series of phenomena concerning hydrogen precipitation in cavities within supersaturated metals. It is assumed that in the fracturing of the deuterium-filled cavities, electric fields of sufficient intensity and duration are created, which produce energetic deuterons and hence neutrons from D(d,n)3He reactions. The mechanism predicts neutron yields compatible with those reported in some of the experiments and implies a certain degree of experimental irreproducibility. The main features of the proposed mechanism are illustrated and discussed in connection with the experimental data.
