Study on the nuclear transitions from the aligned states of the octupole bands in actinides as an example

A simple theoretical model designed for a qualitative analysis of octupole bonds in deformed nuclei (DN) under the conditions of heavy effect of the Coriolis forces is presented. The model is shown to be able to describe typical effects of the rotation bond and oscillation degrees of freedom both in the 0--band spectrum characteristics and in probabilities of E1 transtitions from them to the ground state band. The model allows one to follow changes in the nuclear state structure as aligning an angular momentum (AM). The octupole AM aligning is appreciable even in lower states of rotation bands with a negative parity in actinides. Selectivity of dipole transitions in the 232Th, sup(236, 238)U nuclei must be sufficiently pronounced even at spin I approximately 5 according to the above model. This conclusion corresponds to experimental data. Model conclusions on the effect of forming upon electrical nuclei properties are also confirmed by an experiments
