Oscillating forward angle cross sections for theNi60(O18,O16)Nig.s.62transition

Abstract
The yield of the Ni60(O18, O16)Nig.s.62 reaction at an incident energy of 65 MeV has been measured to forward angles using a QDDD spectrometer. Predicted, strong oscillations in the forward angle differential cross section are indeed observed. The detailed shape of this angular distribution can be reproduced by distorted-wave Born-approximation calculations employing an optical potential more strongly absorbing in the nuclear interior, and more weakly absorbing at the nuclear surface than previously used.
