Abstract: | Excitation functions for the18O(p,n)18F reaction were measured at bombarding energiesE p=4.6 to 6.6 MeV. In and near two resonances of the yield curves atE p=5.622 and 6.061 MeV, angular distributions were measured with neutron time-of-flight techniques. The strong neutron decay to theT=1 state in18F and the similarity of the18O(p,n) and18O(n,n) yield curves give good evidence that the structures in the18O(p,n) yield curve arise from the formation ofT=3/2 states in19F. A two-level-analysis does not give satisfactory fits to the strongly asymmetric angular distributions. |
