| 英文摘要 | Recent experiments open up the possibility to investigate oblate rotation-aligned states and prolate high-K isomers in neutron-rich tungsten isotopes. In the present work, we perform the projected-shell-model calculations for A similar to 190 tungsten nuclei. The W-190 results are compared with experimental data. The observed 8(+) isomer is assigned as a two-quasiproton K (pi) = 8(+) configuration. Low-lying high-K four-quasiparticle states are predicted. Of particular interest is the prediction of the K (pi) = 20(+) state in W-190,W-192, which may form a long-lived spin trap. In competition with the prolate high-K states, rotational alignment leads to near-yrast collective oblate rotation. |
