Abstract Remarkable triaxiality is found in the high-K isomeric states of A ~ 130 nuclei using the configuration-constrained calculations of potential-energy surfaces.
The triaxiality gives the further understanding of the decay properties of the isomers. The calculation with triaxiality can well explain the measured quadrupole moment of the Kπ=7- isomer in130Ce.
