英文摘要	Deformed even-even nuclei Barium isotopes with quadrupole-octupole deformations are investigated on the basis of a collective model. The model describes energy levels of the yrast band with alternating parity in the neutron- rich (140;) (142;) (144;) (146;) Ba-148. The structure of the alternating parity bands is examined by odd-even (Delta I = 1) staggering diagrams. An analytical method of the collective model is proposed for the calculation of E2 transition probabilities in alternating spectra of the nuclei (140;) (142;) (144;) Ba-146.
