γn→π-p process in 4He and 16O

Nuclear transparencies for the fundamental process γn→π-p on 4He and 16O have been calculated using nucleon configurations obtained from realistic ground-state wave functions by the Monte Carlo method. Comparisons between nuclear transparency results using nucleon configurations and the correlated Glauber approximation are made in the case of (e,e'p) on 4He and 16O. Furthermore, nuclear transparencies for the γn→π-p and (e,e'p) processes have been calculated including a color transparency effect. copyright 1996 The American Physical Society
