Abstract: The properties of M1 and E2 transitions in odd-A rare-earth nuclei are investigated by means of the extended particle-rotor model.shows that the effects of hexadecapole deformation of the core and the second-order coriolis interaction in the rotational hamiltonian on the signature-dependence and the values averaged over the signature α=±1/2 of M1 and E2 transition rates in odd-A nuclei can not be neglected.
