The study of the proton-proton collisions at the beam momentum 1628 MeV/c

Abstract

The detailed investigation of the single pion production reactions $pp\to pnπ^{+}$ and $pp\to ppπ^{o}$ at the incident proton momentum 1628 MeV/c has been carried out. The data are analyzed in the framework of the event-by-event maximum likelihood method together with the $pp\to ppπ^{0}$ data measured earlier in the energy region below 1 GeV. At 1628 MeV/c the largest contributions stem from the $^{3}P_{2}$, $^{3}P_{1}$, $^{3}P_{0}$, $^{1}D_{2}$ and $^{3}F_{2}$ initial partial waves.
