Abstract
The energy spectra of particles lighter than the beam have been measured following the bombardment of , , and targets with 72 MeV beams and 72 and 141 MeV beams. All the spectra exhibit broad continuum peaks centered at approximately the beam velocity. The shapes of these continuum structures are rather well reproduced by a fragmentation model which assumes that the unobserved fragment is transferred to the target and which contains no adjustable parameters. The fragmentation spectra on the three targets are very similar in shape. The total yield of fragmentation products is about the same for the and beams at 72 MeV, although the distribution of strength differs. On the other hand, the fragmentation yield of increases by a factor of 5 when the beam energy is raised from 72 to 141 MeV, but the relative distribution of strength remains constant.
