Evidence for the peripheral quasifree nature of single-nucleon removal from /sup 27/Al by 190-MeV. pi. /sup + -/

Journal Article · · Phys. Rev., C; (United States)
A comparison of nucleon-removal differential scattering cross sections at 35/sup 0/ for 190-MeV ..pi../sup + -/ on /sup 27/Al shows p2n removal and single-nucleon removal as the most dominant. Single-nucleon removal is consistent and in good agreement with the one-step-quasifree ..pi..N scattering model, but only if the pion interacts principally with a p2n system. The outgoing nucleon charge exchange probability is measured to be approx.1/3 for approx.16-MeV nucleons. The ..pi..N angular distribution and the proton energy spectrum at 35/sup 0/ also support the one-step-quasifree scattering with the outermost nucleons model.
