Abstract
An analysis of 271 collimated pairs of alpha particles of comparable ranges emitted from interactions of 20 GeV/c protons with the heavy nuclei of emulsion has been made; ~90% of these can be interpreted as due to the decay of 8Be in its ground state. The mean Q value (~0.094 MeV) obtained from the analysis is in good agreement with the expected Q value of the reaction 8Be → 24He. The energy and angular distributions of the 8Be nuclei have been compared with the predictions of the nuclear "evaporation" theory. The parameter values for good fit are found to be: T = 10 MeV, V = 10 MeV, and β = 0.015.
