Search for Fragment Emission from Nuclear Shock Waves

Abstract
Energy spectra and angular distributions have been measured of He3 and He4 fragments emitted from Ag and U targets, bombarded with 2.7-GeV protons, and 1.05-GeV/nucleon α particles and O16 ions. All cross sections increase dramatically with projectile mass. No narrow peaks are found in the angular distributions or in the energy spectra.
