A study of very weak beta decay branches in cobalt 54 has yielded evidence for a second O+→O+ branch at the 45 ppm level. This provides a direct measure of charge dependent mixing. Other experiments included a study of track formation in high-Tc superconductors, a search for isospin-forbidden beta decay branches in chromium 54, a study of ery high spin in isotopes of hafnium, and irradiation of 30 mineral and natural glass samples to study decay tracks. Cyclotron activity centered around the successful production of a 5.6 MeV/nucleon gold beam and a 4.35 MeV/nucleon germanium 76 beam. A diagnostic radial probe head was installed that incorporates a thin wire for better resolution of individual turns, and the electrostatic deflector was modified. (L.L.)
