Antiproton annihilation at rest in nitrogen and deuterium gas

Academic Article


  • Results on antiproton absorption at rest in gaseous nitrogen and deuterium are presented from an analysis of approximately 106 events each taken with a magnetic spectrometer. Inclusive features such as pion and proton multiplicities and spectra are presented. Data relating to absorption modes requiring more than one nucleon, such as the yield, the spectrum, and the exclusive deuterium channels pd-p, K+- are discussed. The fully reconstructable channels pd+ - p,++ - -p also show a high-energy proton tail unaccounted for by single nucleon rescattering mechanisms. © 1989 The American Physical Society.
