Abstract
Differential cross sections for 87Sr(d, p) 88 transitions to the particle-hole states of 88Sr were obtained with the Pittsburgh 18 MeV deuteron beam and the Enge split-pole spectrograph. States of 88Sr up to 7223 keV in excitation were studied with a total resolution of 16 keV. Finite-range and zero-range DWBA predictions were found to be in excellent agreement with each other and also in acceptable agreement with the data. For eleven levels, mixed l = 2 and l = 0 transitions were identified. Residual interaction matrix elements for the (1 g −1 9 2 2 d 5 2 ) multiplet were derived from the 88Sr data. Two potentially divergent results of 91Zr(p, d) 90Zr and 91Zr( 3He,α) 90Zr reactions for the (1 g −1 9 2 2 d 5 2 ) multiplet in 90Zr can be reconciled by allowing for l n mixing. The revised 90Zr matrix elements are compared with the 88Sr result.
