PROPERTIES OF OCTUPOLE STATES 238U

The energies and electrical properties of the octupole states of the 238U nucleus are studied within theframework of a phenomenological model considering the Coriolis mixing of rotational bands. Mixing ofthe low-lying negative parity bands is considered. The energies, the structures of states of rotational bandswith Kπ=0−,1−,2−,3− and the reduced probabilities of Е1 transitions are calculated. Theoretical energyvalues and Е1-transitions’ probabilities are compared with the experimental data. Good agreement betweenexperimental data and theoretical results is obtained.
