Abstract：
Configuration-constrained potential-energy-surface calculations have been performed to investigate the K isomerism in the proton-rich A~80 mass region. An abundance of high-K states are predicted. These high-K states 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-K states may indicate a combination of K isomerism and shape isomerism.
