The reaction p + p yields d + pi /sup +/ in the Bev region is studied within the one-pion-exchange model with final-state interaction between the neutron and proton to form the deuteron. A simple approximate evaluntion of the loop integral gives the final differential cross section in terms of the pionnucleon coupling constant, the deuteron wave function normalization, the pi p elastic scattering cross section, and the Ferrari-Selleri form factor. Comparisons with the limited experimental results are made, and fairly good agreement is obtained. The large forward scattering cross section near c.m. energy 3.0 Bev is explained in terms of the large backward pi /sup +/p elastic scattering cross section at pi p c.m. energy 1.92 Bev STAI = 3/2, J = 7/2(?) resonancel. Further implications of the calculation are discussed. (auth)
