英文摘要: Inspired by the recent experimental identification of the new isomer with a half-life of (620 +/- 150) ns in the very neutron-rich nucleus Zr-108, we apply the projected shell model with axially-deformed bases to discuss possible shapes near the ground state and the nature of the isomer. The structure of the new isomer is investigated by restricting the calculation to prolate and oblate shapes. It is shown that the isomer can be understood as a K-isomer. Meanwhile, the calculation predicts more low-lying high-K configurations, which may be confirmed by future experiments.
