Clover detector has been used as a Compton polarimeter to measure the linear polarization of -rays produced in heavy ion fusion reaction. The polarization sensitivity of the clover detector has been measured over -ray energies ranging from 386 to 1368 keV. The E1 multipolarity of the 1117 keV transition in Rh has been established using this polarimeter. This has resulted in the assignment of negative parity to the band head at 3710 keV in Rh.

In-beam ␥-ray spectroscopic studies of the Nϭ50 nucleus 92 Mo, up to spins of Jϳ18ប and E x ϳ12 MeV, are reported using a heavy ion fusion reaction with a 28 Si beam at an incident energy of 138 MeV on an isotopically enriched 74 Ge target. Sixteen new transitions belonging to this nucleus have been observed and placed in the decay scheme using the conventional ␥-␥ coincidence data. The level scheme derived from these measurements is compared with shell model calculations. The presence of gamma rays with E ␥ ϳ2 MeV at Jϳ14ប is indicative of the breaking of the Nϭ50 core. The occurrence of gamma rays with E ␥ ϳ2 MeV at low spins (Jϳ8ប) indicates the excitation of protons across the Zϭ38 core. This is supported by large-basis shell model calculations. The deduced level scheme exhibits single-particle behavior up to the highest observed spins and excitation energies.
