ANGULAR DISTRIBUTION OF FRAGMENTS FROM FISSION INDUCED BY HEAVY IONS IN GOLD AND BISMUTH
ABS>Measurements of the angular distribution of fission fragments produced by irradiation of Au/sup 197/ and Bi/sup 209/ with various heavy ions were presented. The projectiles (B/sup 11/, C/sup 12/ N/sup 14/, and O/sup 16/) had energies from a few Mev above the Coulomb barrier to 10.4 Mev per nucleon. The gross features of these results could be explained by use of a model and parameters originally developed to account for angular distributions of fission fragments from helium-ion bombardments. In detail, however, these results indicated that the models used to predict the average value of the angular momentum of the compound nucleus gave values too low near the Coulomb barrier. Furthermore, at high bombarding energies it was necessary to consider the fact that appreciable direct interaction was taking place. (auth)
