Proton-neutron interactions in nuclei with A∼90

An extension of the cluster-(quadrupole-octupole) phonon model is proposed for nuclei with A∼90 to describe simultaneously positive- and negative-parity states, in which quadrupole as well as octupole vibrations of the88Sr core are allowed. The cluster states include particle and particle-hole core...
