Solutions applicable for all interaction strengths are obtained for a schematic Hamiltonian with pairing forces and particle-hole octupole-octupole forces. The method is applied to the light U isotopes. Adjusting the particle-hole interaction strength to the measured excitation energies leads to an immediate explanation for the low-lying excited states in this region.
