This work is part of a program partially supported by Comision Asesora de Investigacion Cientifica y Tecnica.It is shown that the minimum solitary wave of a nonlinear spinorial model is unstable under charge-preserving deformations via a radiative decay. We analyze the cause of this decay.engjournal articlehttp://dx.doi.org/10.1103/PhysRevD.34.644http://journals.aps.org/open access53Física (Física)22 Física
