Final state interactions in nuclear pion photoproduction over the (3, 3) resonance

An impulse approximation calculation is made on the reaction ⁵¹V(γ, π⁺)⁵¹Ti from the region just above photopion threshold to the tail of the (3, 3) resonance. Pion final state distortions are taken into account through realistic optical potentials. Results are compared to those for plane-wave and surface-produced pions and to recent experiment. Comparison is made between surface-produced pions and pions distorted by the s-wave component of the optical potential.
