  It is generally accepted that the pulsar magnetic field converts most of its
rotational energy losses into radiation. In this paper, we propose an
alternative emission mechanism, in which neither the pulsar rotational energy
nor its magnetic field is involved. The emission mechanism proposed here is
based on the hypothesis that the pulsar matter is stable only when moving with
respect to the ambient medium at a velocity exceeding some threshold value. A
decrease in velocity below this threshold value leads to the decay of matter
with the emission of electromagnetic radiation. It is shown that decay regions
on the pulsar surface in which the velocities of pulsar particles drops to
arbitrarily small values are formed under simple driving condition. It is also
shown that for the majority of pulsars having measured transverse velocities,
such a condition is quite possible. Thus, the pulsar radiation carries away not
the pulsar rotational energy, but its mass, while the magnitude of the
rotational energy does not play any role. At the end of the paper, we consider
the reason for the possible short-period precession of the pulsar.
