ANGULAR-MOMENTUM TRANSFER IN DEEPLY INELASTIC-COLLISIONS FROM EXCLUSIVE SEQUENTIAL-FISSION EXPERIMENTS

Kinematically complete experiments have been performed on the three-body exit channels in 7.5 MeV/amu Pb208 and U238 on Ni58 and Zr90. The bulk of the events (>99%) can be interpreted as sequential fission following deeply inelastic collisions. From the angular correlations, oriented-spin values up to 45 are deduced for the heavy fissioning fragment. Their constancy at large energy losses points to strong fluctuations in the correlation between energy loss and angular momentum. © 1979 The American Physical Society.
