Reaction /sup 58/Ni(. pi. /sup +/,2p-italic) at 160 MeV

Journal Article · · Phys. Rev. Lett.; (United States)
Data for the /sup 58/Ni(..pi../sup +/,2p-italic) reaction at T-italic..pi.. = 160 MeV were obtained for a number of angle pairs. The resultant angular correlations for T-italic/sub 1/+T/sub 2/>160 MeV (guaranteed pion absorption) peak at a separation angle corresponding to absorption on a deuteron at rest. However, simple estimates of initial- and final-state scatterings suggest that less than 50% of the absorption cross section arises from absorption on nucleon pairs. The data show little evidence for scattering of pions before absorption on nucleon pairs.
