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 E 1 transitions in nuclei 153, lSSEu and lss, 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 in E I(AK=0) transitions whereas E I(IAKI = 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" in E 1 transitions between the low-lying states. The obtained results are analysed in detail.
