Differential ranges of /sup 44/Sc/sup m/, /sup 46/Sc, /sup 47/Sc, and /sup 48/Sc emitted at 90/sup 0/ to the beam in the interaction of /sup 238/U with 0.8, 3.0, 11.5, and 400 GeV protons have been measured and transformed to the corresponding energy spectra. The mean fragment energies decrease from 83 +- 5 to 58 +- 4 MeV between 0.8 and 11.5 GeV and to 50 +- 3 MeV at 400 GeV. The widths of the spectra increase markedly with energy up to 11.5 GeV and more slowly thereafter. Isotopic differences are minor although the spectra of neutron-deficient /sup 44/Sc/sup m/ are somewhat broader, particularly at 0.8 GeV. The results are compared with the statistical fragment emission model and discussed in terms of asymmetric binary fission and deep spallation mechanisms.
