RESEARCH ON HIGH ENERGY ANTIPARTICLE INTERACTIONS
Abstract
One of the main lines of the research presented concerns the interaction of antiprotons of 2 GeV/c momentum with the nuclei of nuclear emulsions. The final analysis has to be preceded by an extensive analysis of interactions caused by negative pions of the same momentum. These results together with the angular and the energy distribution of the secondary pions and the energy distribution of knock-on protons agree quite well with a cascade calculation based on a knowledge of elementary processes, mainly pion scattering, production and absorption. The new experimental reslts thus remove the necessity to consider as severe the bad agreement between an earlier experiment and the cascade calculations. Further the observation of K-mesons produced by pions indicate a low cross section for K-meson production. (Author)
