Book Description
This report is a review of the activities of the period from August 1, 1981 through August 31, 1982. The final analysis of pi-zero production in heavy ion collisions representing experiments at the Bevalac with a system previously described is completed. The main results involve cross sections for central collisions resulting in the production of pi-zeros, charged pions, and proton multiplicities, and some results of correlations and low energy gamma radiation. Results from the alpha-alpha experiment at the CERN ISR are included in the form of a published paper and an outline of papers that are in press. A short report of a collision effect in an anomalon experiment is included as well. The energetic particle spectra from .mu.−-capture in medium heavy nuclei were studied at TRIUMF, using the large scintillation counters for neutron and proton detection and multiple Ge(Li) and NaI(Tl) counters. The preliminary analysis indicates the presence of such an unusual energetic component. The measurement of the particle and .gamma.-ray correlation in .pi.−-capture in 165Ho was completed during this year, and the data analysis is continuing in order to elucidate the discrete spectral features, high spin generation and other correlations. A measurement was finished in our search for a new type of strong perturbation of pionic x-ray by the use of coincidences between pionic x-rays and .gamma.-rays from a deformed nuclei.
