Abstract：
Configuration-constrained potential-energy-surface calculations have been performed to investigate the Kisomerism in the proton-rich A~80 mass region. An abundance of high- Kstates are predicted. These high- Kstates arise from two and four-quasi-particle excitations, with K ^π=8 ⁺and K ^π=16 ⁺, respectively. Their excitation energies are comparatively low, making them good candidates for long-lived isomers. Since most nuclei under study are prolate spheroids in their ground states, the oblate shapes of the predicted high- Kstates may indicate a combination of Kisomerism and shape isomerism.
- isomer,
- high-K,
