Abstract

Double-differential cross sections have been measured for high-energy $p$ , $d$ , $t$ , ${}^{3}{He}$ , and ${}^{4}{He}$ particles emitted from uranium targets irradiated with ${}^{20}{Ne}$ ions at energies of 250, 400, and 2100 MeV/nucleon and ${}^{4}{He}$ ions at 400 MeV/nucleon. By using the shape and yield of the proton energy spectra, the shape and yield of the $d$ , $t$ , ${}^{3}{He}$ , and ${}^{4}{He}$ energy spectra can be deduced at all measured angles for all incident projectile energies by assuming that they are formed by a coalescence of cascade nucleons, using a model analogous to that of Butler and Pearson, and Schwarzschild and Zupančič.
