Abstract

We have recently reported the experimental results of charged pion photoproduction from carbon in an energy range between 300 and 850 MeV of the incident photons1. Momentum spectra at lab angles 28.4° and 44.2° have been measured and in these spectra clearly revealed are the striking features characteristic of the quasi-free production (QFP) of the pions. The data have in fact been well reporduced by a plane-wave impulse approximation (PWIA) calculation in which pion absorption due to the final state interactions is properly taken into account.
