Abstract
The energies and wave functions of the nonrotational states below 2.3 MeV in 156Gd and 158Gd are calculated within the quasiparticle-phonon nuclear model. It is shown that the wave functions have the dominating one-phonon component. The contribution of the two-phonon configurations to the wave function of the excited states is less than 10%. The calculated excitation energies and B(E; λ = 2, 3, 4) values for transition from the ground state are found to be in agreement with experimental data. High intensities of the one-nucleon transfer reactions are explained by the corresponding large two-quasiparticle components of the one-phonon terms of the wave functions. The calculated intensities and reduced probabilities of the E1, E2, and M1 transitions between excited states are in reasonably good overall agreement with experimental data.
