Neutron particle-hole states in Sr88 have been studied by means of the reaction Sr87(d,p)Sr88 at Ed=12 MeV. It has been determined that the earlier reported transitions to presumed states at 4744 and 5780 keV in Sr88 arise mainly from transition to the ground state and the first excited state in Sr89. Spectroscopic strengths for states of the multiplets [g92-1d52] and [g92-1s12] have been determined by detailed distorted-wave Born-approximation analysis. Jπ assignments are suggested on the basis of sum rules and comparison with other experiments. Matrix elements for two-particle effective interactions are derived.
