dc.description.abstractEnIn this work we report on recent microscopic calculations of K-isomeric states of two-quasiparticle character in well-deformed rare-earth nuclei and actinide nuclei. In these calculations we employ a Skyrme energy-density functional together with a seniority residual interaction in the Hartree-Fock-BCS approximation with selfconsistent blocking (SCB). The strength of the seniority interaction is calibrated in a consistent way: as some of us showed in Ref. [1] for rare-earth nuclei, the same strength can be obtained in a fit on moments of inertia of even-even nuclei and in a fit on odd-even mass staggering. The former fitting protocol is used for the actinide nuclei studied here. Once the seniority force was adjusted we calculated properties of various K-isomeric states without additional parameters. Overall we have obtained a rather good agreement with available data around ^154Nd and in the ^234U ? ^236Pu region. We also found that an octupole deformation lowers the excitation energy of the K^pi = 6^- isomer in ^234U.
