Abstract

Excited states in the neutron-deficient nuclide 163W were investigated using the 106Cd(60Ni,2pn)163W reaction at a beam energy of 270 MeV. The level scheme for 163W was extended significantly with the observation of five new band structures. The yrast band based on a 13/2+ isomeric state is extended up to (57/2+). Two band structures were established on the 7/2− ground state. Quasiparticle configuration assignments for the new band structures were made on the basis of cranked Woods-Saxon shell-model calculations. The results reported in this article suggest that the negative-parity ν(f7/2,h9/2) orbitals are responsible for the first rotational alignment in the yrast band.
