Abstract It is shown within the microscopic approach combining the quasiparticle-phonon nuclear model and the nonadiabatic rotational model (QPNM + NRM) that a complicated behaviour of E1 transitions in nuclei153,155Eu and155,157Tb can be described only if both the Coriolis and quasiparticle-phonon interactions are taken into account. In contrast with the results obtained in the NRM allowing for pairing and the Coriolis forces only, QPNM + NRM calculations provide a considerable increase inE1(ΔK=0) transitions whereasE1(¦ΔK¦=1) transitions can undergo either increase or essential decrease. We also describe the low-lying states of the considered nuclei and demonstrate the decisive role of the giant dipole resonance “tail” inE1 transitions between the low-lying states. The obtained results are analysed in detail.
