Scientific paper

Since the discovery of supernova 1987A several authors have noted that it may provide an excellent opportunity to observe the cosmic ray output of a young pulsar through the "beam dump" that the supernova ejecta provide. It has been suggested that neutrino emission from p-p collisions is possible. In this letter the authors argue that the cosmic abundances of Li, Be and B set significant constraints on the comsic ray proton production in the young (t ≤ 1 yr) remnant, and, in particular, rule out neutrinos from shock-accelerated protons in the ejecta at currently detectable levels.
