Abstract
Thirteen energy levels in Sr89 were excited by the Sr88(d, p)Sr89 reaction. The excitation energies of the levels are 0, 1.04, 2.00, 2.44, 2.67, 3.18, 3.45, 3.74, 4.10, 4.44, 4.60, 4.97, and 5.38 Mev. The ground-state Q-value is 4.15 ± 0.04 Mev. Angular distributions were measured for protons leaving Sr89 in the first three levels and for the 3.74-Mev state. Spin assignments were made using the shell model and the DWBA stripping theory. The assignments are 2d5/2 for the ground state, 3s1/2 for the 1.04-Mev state, 2d3/2 for the 2.00-Mev state, and [Formula: see text] for the 3.74-Mev state. The results are compared with analogous data on Zr91 levels.
