Description

The Nuclear Physics Laboratory of the University of Washington has for over 40 years supported a broad program of experimental physics research. Some highlights of the research activities during the past year are given. Work continues at a rapid pace toward completion of the Sudbury Neutrino Observatory in January 1997. Following four years of planning and development, installation of the acrylic vessel began last July and is now 50% complete, with final completion scheduled for September. The Russian-American Gallium Experiment (SAGE) has completed a successful {sup 51}Cr neutrino source experiment. The first data from {sup 8}B decay have been taken ... continued below

Description

The Nuclear Physics Laboratory of the University of Washington has for over 40 years supported a broad program of experimental physics research. Some highlights of the research activities during the past year are given. Work continues at a rapid pace toward completion of the Sudbury Neutrino Observatory in January 1997. Following four years of planning and development, installation of the acrylic vessel began last July and is now 50% complete, with final completion scheduled for September. The Russian-American Gallium Experiment (SAGE) has completed a successful {sup 51}Cr neutrino source experiment. The first data from {sup 8}B decay have been taken in the Mass-8 CVC/Second Class Current study. The analysis of the measured barrier distributions for Ca-induced fission of prolate {sup 192}Os and oblate {sup 194}Pt has been completed. In a collaboration with a group from the Bhabha Atomic Research Centre they have shown that fission anisotropies at energies well above the barrier are not influenced by the mass asymmetry of the entrance channel relative to the Businaro-Gallone critical asymmetry. They also have preliminary evidence at higher bombarding energy that noncompound nucleus fission scales with the mean square angular momentum, in contrast to previous suggestions. The authors have measured proton and alpha particle emission spectra from the decay of A {approximately} 200 compound nuclei at excitation energies of 50--100 MeV, and used these measurements to infer the nuclear temperature. The investigations of multiparticle Bose-Einstein interferometry have led to a new algorithm for putting Bose-Einstein and Coulomb correlations of up to 6th order into Monte Carlo simulations of ultra-relativistic collision events, and to a new fast algorithm for extracting event temperatures.
