Collective excitations of even axial nuclei

Abstract

The collective excited states of axial even nuclei are considered with the interaction of the rotation with β- and γ-oscillations taken into account. The expression for the wave functions and energy levels are obtained as expansions in inverse powers of the rigidity parameters of β- and γ-oscillations. The reduced probabilities of E2 transitions between these states are calclated. The results are compared with experimental data and the theory of non-axial nuclei. The possibility of establishing experimentally the nature of excited 0 + states is discussed.
