The angular-momentum-bearing degrees of freedom involved in the fission process are identified and their influence on experimental observables is discussed. The excitation of these modes is treated in the “thermal” limit and the resulting distributions of observables are calculated. Experiments demonstrating the role of these modes are presented and discussed.

Particle-particle coincidence measurements have been made between light charged particles (1,2,3H and He4) produced in the reaction (8.5 MeV/nucleon) 56Fe+natAg. This coincidence requirement emphasizes central collisions leading to evaporation residues. Average multiplicities are found to be approximately three alphas and approximately four protons per evaporation residue; these values imply that approximately (1/2 the initial excitation energy of about 211 MeV is evacuated from the evaporation residues by these particles. This fractional energy evacuation by charged particles is considerably larger than that found for the similar reaction (8.5 MeV/nucleon) Ag40. In both reactions the effective emission barriers for H1 and He4 …
