Abstract

Angular distributions of differential cross sections and polarization analyzing powers are presented for the 1H(p, π+)2H reaction for incident proton energies between 305 and 425 MeV. The pions were detected in a single-arm configuration employing a magnetic spectrograph. Pions associated with both bound (deuteron) and unbound final nucleon states were detected simultaneously. These data provide the first indication of the contribution of d-wave pions in this energy region. Some data concerning the analyzing power for the inclusive pions from the 1H(p, π+)pn reaction are also presented. An interesting feature of these results is the similarity of the analyzing power for the 1H(p, π+)pn reaction (when the relative kinetic energy in the pn system is 10–20 MeV) to that for 1H(p, π+)2H.
