Abstract
AMONG the possible interpretations of the neutro-electric effect, recently discovered by Kikuchi, Aoki and Husimi1, the disintegration of the neutron into an electron and a proton must be discarded, since Gilbert, Smith and Fremlin2 could find no corresponding track in the Wilson chamber. (Their estimation that about thirty proton-electron pairs should appear per expansion is no doubt too large; but our present result is also in contradiction to the view of disintegration.) The most reasonable explanation would be to assume the expulsion of the orbital electron or the electron in a negative state due to some still unknown interaction between the electron and heavy particles. In this process, as the neutron loses its energy, the atom with which collision has occurred should gain the corresponding momentum. Therefore, the electron track starting in the Wilson chamber should always be accompanied by a track of a heavy particle.
