  In this work it is shown, that for short 3ns neutrino pulses reported by
OPERA, a relativistic shape deforming effect of the neutrino distribution
function due to spontaneous emission, produces an earlier arrival of 65.8ns in
agreement with the reported 62.1ns\pm 3.7ns, with a RMS of 16.4ns explaining
the apparent superluminal effect. It is also shown, that early arrival of long
10500ns neutrinos pulse to Gran Sasso, by 57.8ns with respect to the speed of
light, could be explained by a shape deforming effect due to a combination of
stimulated absorption and spontaneous emission, while traveling by the decay
tunnel that acts as a LASER tube.
