Abstract

The interrelation between the octupole phonon and the low-lying proton-neutron mixed-symmetry quadrupole phonon in near-spherical nuclei is investigated, The one-phonon states decay by collective E3 and E2 transitions to theground state and by relatively strong El and M1 transitions to the isoscalar 2(1)(+) state. We apply the proton-neutron version of the interacting boson model including quadrupole and octupole bosons (sdf-IBM-2). Two F-spin symmetric dynamical symmetry limits of the model, namely the vibrational and the gamma-unstable ones, are considered. We derive analytical formulae for excitation energies as well as B(E1), B(MI), B(E2) and B(E3) values for anumber of transitions between low-lying states. (C) 2000 Elsevier Science B.V.
