Angular-Momentum-Bearing Modes In Fission, Luciano G. Moretto, Graham F. Peaslee, Gordon J. Wozniak Oct 1989

Angular-Momentum-Bearing Modes In Fission, Luciano G. Moretto, Graham F. Peaslee, Gordon J. Wozniak

Faculty Publications

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.

Conformal Transformations In Quantum Mechanics, Alec Schramm, Alfons Stahlhofen

Alec J Schramm

We discuss the occurrence of orientation- or area-preserving diffeomorphism groups in quantum mechanics. We show that the generators of these groups are contained in the generators of the symmetry group of a central potential, as is demonstrated by the example of the Coulomb problem. Our approach is based on the recently introduced concept of a factor space of scattering states.


Particle-Particle Coincidence Measurements For 1,2,3h And 4he In The Reaction 480 Mev 56fe + Natag, Graham F. Peaslee, N. N. Ajitanand, John M. Alexander, Roy Lacey, L. C. Vaz, Morton Kaplan, M. Kildir, D. J. Moses, D. Logan, M. S. Zisman Feb 1989

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 …

The Bay Study Group was created by the City of Tampa in 1976 to monitor the effects of pollution abatement that occurred in Hillsborough Bay when the city’s wastewater treatment plant was upgraded from primary to advanced treatment in 1979. The Bay Study Group documented a remarkable restoration of water quality parameters and biological indicators in Hillsborough Bay from the mid 1980s until 2009, when it was disbanded. This zip Geodatabase file contains the aerial photos for the year 1989.
