States of 87Sr populated by deuteron pick-up from 89Y

The reaction 89Y(d, α)87Sr has been observed at a bombarding energy of 12 MeV. Angular distributions of the emitted α-groups were recorded over the angular range 10° to 160° lab and compared with a DWBA analysis. Many levels in 87Sr appear to be populated by proton pickup from the 2p32 orbit. The levels of 87Sr populated in this reaction correspond to those observed in the 87Rb(p, n)87Sr reaction but differ to a large extent from those seen in neutron stripping and pick-up reactions.
