A1 - Gutbrod, Hans Herbert A1 - Sandoval, Andres A1 - Stock, Reinhard T1 - Search for Fragment Emission from Nuclear Shock Waves T2 - Physical review letters N2 - Energy spectra and angular distributions have been measured of 3He and 4He fragments emitted from Ag and U targets, bombarded with 2.7-GeV protons, and 1.05-GeV/nucleon alpha particles and 16O ions. All cross sections increase dramatically with projectile mass. No narrow peaks are found in the angular distributions or in the energy spectra.
