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

Abstract

The detailed investigation of the single pion production reactions $pp\to pn{\pi }^{+}$ and $pp\to pp{\pi }^o$ 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 $pp\to pp{\pi }^0$ 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.
