Abstract
IT has been suggested1,2 that high energy cosmic rays originate in pulsars. If this is true, it is conceivable that the pulsars might also be emitting ultra high energy, pulsed gamma rays with the same periodicities as observed at radio frequencies. These gamma rays might be the result of either the decay of π0-mesons or the bremsstrahlung of electrons in the regions surrounding the pulsars. There is no precise theory yet on this aspect. There have already been several searches for high energy gamma rays from pulsars3–5.
