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

Differential cross sections of the reactions pp --> d pi(+) and pp --> pn pi(+) have been measured at T-p = 400 MeV by detecting the charged ejectiles in the angular range 4 degrees less than or equal to Theta(Lab) less than or equal to 21 degrees. The de
