Abstract
Realistic wave functions are used to calculate threshold photoproduction from in the impulse approximation. The effects of the -state components, the Coulomb interaction in , and the nuclear size on this cross section are investigated. In particular, it is argued that since realistic forces underbind and produce too large a radius, such model calculations should be expected to give (approximately 10%) too small a cross section. The resulting theoretical estimate is in reasonable agreement with experimental data.
