Cluster (quadrupole-octupole) phonon model: Application to Y89
A cluster-phonon model is proposed for odd-mass nuclei to describe simultaneously positive- and negative-parity states, in which octupole as well as quadrupole vibrations of the core are allowed. The cluster states include one-particle and two-particle-one-hole excitations. The residual interaction...
