Vp. Andreev et al., EXPERIMENTAL-STUDY OF THE REACTION PP-]PP-PI(0) IN THE ENERGY-RANGE 600-900 MEV, Physical review. C. Nuclear physics, 50(1), 1994, pp. 15-23
The detailed study of the reaction pp --> pppi0 was carried out at sev
en energies of the incident proton in the region 600-900 MeV. Energy s
pectra, angular, and effective mass distributions were analyzed. The a
nalysis was performed in the framework of the one-pion exchange model.
Taking into account only the P-33 wave in the pole diagrams allows on
e to obtain good agreement with experimental data on various different
ial distributions. At the same time the predictions for total cross se
ctions are much lower than the experimental data.
