  The theory pioneered by Blasone and Vitiello describes massive neutrinos as
generalized coherent flavor eigenstates within the extended Standard Model. In
this paper, we compute the neutron beta decay spectrum for the Blasone-Vitiello
theory in a model with two neutrinos. For relativistic neutrinos, the obtained
spectrum is in agreement with the Standard Model. However, there are
discrepancies when the kinetic energy of the electron is close to the end point
energy. The possibility of measuring the discrepancies in future experiments is
discussed.
