In-beam spectroscopic studies of /sup 66/Ge and in /sup 74/Kr have been made via the heavy ion reactions /sup 58/Ni(/sup 10/B,pn)/sup 66/Ge and /sup 60/Ni(/sup 16/O,2n)/sup 74/Kr, by using the Oak Ridge National Laboratory EN tandem Van de Graaff accelerator to produce the boron and oxygen beams. Gamma-gamma and ..gamma..(THETA) measurements have been made with Ge(Li) detectors. New levels have been added to the /sup 66/Ge decay scheme including yrast states up to tentative (10+) level, and spin parity assignments have been made for several levels. In /sup 74/Kr, the 6+ yrast level and a possible 8+ level have been identified. The levels in /sup 66/Ge and in /sup 74/Kr have been calculated in the Interacting Boson Model and compared to the observed levels. Two-quasiparticle-plus-rotor model calculations have been performed for /sup 76/ /sup 78/ /sup 80/Kr, as well as for /sup 66/Ge and compared with experiment. These calculations nicely reproduce the negative parity band beginning at 5- which are seen in all these nuclei and the positive parity band in /sup 80/Kr that begins at 8+.
