High-spin Spectroscopy in $^{163}$Hf
ORAL
Abstract
High-spin states of the odd-A nucleus $^{163}$Hf were populated through the $^{74}$Ge($^{94}$Zr,5n) reaction. Decay $\gamma$ rays were measured with the Gammasphere spectrometer array at ANL. Only two bands were known previously, the lowest one-quasiparticle band based on the neutron $i_{13/2}$ orbital and an excited negative-parity band (ABF) [1]. One band was extended to higher spin and more than eleven new bands observed, most of which were linked to each other. Spins and parities of levels were determined based on the measured multipolarities of $\gamma$ rays. The results will be discussed within the framework of cranked shell model calculations. \\[4pt] [1] K. P. Blume {\it et al}., Nucl. Phys. A 464, 445 (1987).
