Importance of nonanalog nucleon charge exchange transitions in pion knockout reactions
Journal Article
·
· Phys. Rev., C; (United States)
Complete analog dominance in the nucleon charge exchange transitions affecting ratios of (..pi..,..pi..N) cross sections near the (3,3) resonance is experimentally unfounded. No dramatic jumps with neutron number in neutron removal ratios are now expected. There may be a vestige of analog dominance in the deviation of sigma (..pi../sup +/,..pi../sup +/p)/sigma (..pi../sup +/..pi../sup 0/p) from the impulse approximation. Disagreement of an intranuclear cascade calculation with the nucleon charge exchange model (and experiment) is also discussed.
