Abstract

The Sr86(He3,d)Y87 reaction was studied at a laboratory beam energy of 20 MeV to test the possible closed-subshell behavior of the 38-proton configuration. The ground-state Q value is found to be 0.346 ± 0.015 MeV. Several new states were identified below an excitation energy of 3.45 MeV. A distorted-wave analysis was used to assign l values for the stripping transitions. Spectroscopic strengths agree well with sum-rule expectations for the 2p, 1f, and 1g72 configurations. Comparison with the results of Picard and Bassani for the Sr88(He3,d)Y89 reaction indicates qualitative agreement with shell-model expectations for 2p and 1g strengths but significant deviations for 1f strength and for low-lying 2d strength.
