Observation of strong final-state effects in pi+ production in pp collisions at 400 MeV

A. Betsch, R. Bilger, W. Brodowski +29

Differential cross sections of the reactions $pp\to d{\pi }^{+}$ and $pp\to pn{\pi }^{+}$ have been measured at $T_p=400$ MeV by detecting the charged ejectiles in the angular range $4^0 \le…
