Neutrinoless neutron decay feasibility

Within nonrelativistic quantum mechanics, it is shown that there is a virtual level in the energy spectrum of the electron moving in the neutron magnetic field considered as a spherical permanent magnet field. This means that the electron capture by the neutron is possible which, in turn, makes it possible to predict the neutrinoless neutron decay in which the captured electron plays the role of missing neutrino. Either produced electron can again undergo neutron capture, thus triggering a chain reaction, i.e., a certain cascade process. Such a chain reaction can be observed if it breaks. It is difficult to distinguish this break from the ordinary neutron beta decay, since the spatial and temporal resolution of modern detectors does not allow detection of cascade electrons.
