Abstract
The total cross sections relative to photoproduction off the proton have been measured for the reactions (,) and (,) over the energy region from the production threshold up to 12 MeV over threshold. A distorted wave impulse approximation calculation has been performed for the (,) reaction and is seen to be ≃ 30% higher than the observed cross section from threshold to 10 MeV. The (,) reaction represents the first (,) measurement near threshold in which the cross section is not dominated by the term in the production Hamiltonian.
