A new program studying the behavior of nuclear matter under very high excitation was begun at the Bevatron with experiments designed to study the gamma radiation emitted from central collisions of heavy ions. A system was partially completed that made use of a multiplicity detector as a signature of a central collision. The system was surrounded by gamma detectors for both the nuclear and high-energy range; such an arrangement yielded a very large acceptance. A preliminary experiment showed the feasibility of the system and gave the first results of correlations of gamma rays with such collisions. Some details of both the system and the preliminary results are described. Experiments on the measurement of nuclear moments from beta emission are reviewed, and the final results for the latest measurements on /sup 9/Li are given. Results of recent measurements on gamma polarization from high-spin states of /sup 105 -109/Cd are also presented. Studies of electrons resulting from heavy ion collisions using a special high-acceptance beta spectrometer are described. The preliminary results indicate the beginnings of effects that are complements of the so-called combined atom x-ray phenomena. A new program for the study of gamma rays and neutrons produced in the capture of pi meson of nuclei are described with some new results on the excitation of high-spin states. Finally, a reprint of a recent evaluation of some old data concerned with the conserved vector current theory is added.
