[en] The neutron-gamma ray coincidence spectra following π^- capture in ¹⁶⁵Ho and ¹⁸¹Ta are analyzed. Although interesting correlations between the yield of gamma rays and the neutron energy are observed, more data are necessary. 4 figures

[en] This report reviews activities for the period from August 1, 1978 through July 31, 1979. Four experiment reports and a list of publications are included. Separate abstracts were prepared for unpublished data

[en] The second phase of an experiment studying matter at very high excitation following central collisions between ¹²C and ²⁰⁸Pb at 1.05 to 2.1 GeV/n was completed with a run at the Berkeley Bevatron in February, 1979. This phase was designed to obtain the production cross sections for π⁰ mesons as a function of energy. Such an energy scan could, in principle, indicate extraordinary changes in production cross sections and signal the creation of a different state of nuclear matter. A description of the improved system together with a preliminary version of the new results is given. Rates of γ and charge production are plotted as a function of beam energy. 10 figures
