Double differential cross sections have been measured for high energy p,d,t, /sup 3/He, and /sup 4/He particles emitted from uranium targets irradiated with /sup 20/Ne ions at 250, 400, and 2100 MeV/nucleon and /sup 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, /sup 3/He, and /sup 4/He energy spectra can be deduced at all measured angles for all incident projectile energies assuming that they are formed by coalescence of cascade nucleons. Finally, it is found that the overall features of the proton inclusive spectra are fit without any adjustable parameter by a proposed nuclear fireball model. In this model the nucleons which are mutually swept out from the target and projectile form a hot quasi-equilibrated fireball which decays as an ideal gas.
