Abstract
Cross sections of antinucleus (p¯, d¯, t¯, He¯3, He¯4) interactions with nuclei in the energy range 100 MeV/c to 1000 GeV/c per antinucleon are calculated in the Glauber approximation which provides good description of all known p¯A cross sections. The results were obtained using a new parameterization of the total and elastic p¯p cross sections. Simple parameterizations of the antinucleus-nucleus cross sections are proposed for use in estimating the efficiency of antinucleus detection and tracking in cosmic rays and accelerator experiments. These parameterizations are implemented in the Geant4 toolkit.
