Abstract

To study properties of the states of negative parity in deformed nuclei a phenomenological mode which takes into account the Coriolis coupling of the octupole bands is proposed. The diabatic characteristics of dipole electric transitions are investigated by introducing a parametrization of the intrinsic m.e.(matrix element) of the operator which generates the dipole {gamma}-transitions. This operator includes both the dipole electrical and dipole toroidal moments influence. The calculations for the isotopes {sup 220,226}Ra have been performed. The energy spectra and E1-, E2- and E3-transition probability have been calculated. The m.e. values of the toroidal moment are obtained. The calculation for the energy weighted sum rule for E1-transitions has been done. The contribution of the toroidal moment to the sum rule has been estimated. (author). 15 refs.; 4 figs.; 7 tabs.
