DESCRIPTION OF NONROTATIONAL STATES OF CF-250 AND FM-256

Low-energy nonrotational states of Cf-250 and Fm-256 are calculated in the framework of a quasiparticle-phonon nuclear model. A qualitativel y correct description of the available experimental data is obtained, and some predictions are made. It is shown that the wave functions of 1.8-MeV states have predominant one-phonon components. The energies an d structure of high-K states in Cf-250, Fm-250, Fm-256, No-254, and (2 60)104 are calculated. High-multipole interactions lead to mixing of t wo-quasineutron and two-quasiproton configurations in the K(pi) = 4- s tates of Cf-250, the K(pi) = 5+ states of Fm-256, and the K(pi) = 5- s tates of (260)104.
