Radiator-particle-coupling model for /sup 89/Y excited states

The low lying excited states of /sup 89/Y are calculated by treating the nucleus as a deformed /sup 88/Sr rotator coupled to a single valence proton. The unknown spins and parities of three excited levels are predicted by this model. The model matches experiment for the spin, parity and sequence of seven other states of excitation less than 3 MeV. This model will predict smaller electromagnetic M4 matrix elements in /sup 89/Y than does the usual shell model, perhaps resolving a discrepancy between theory and experimental lifetimes.
