Abstract:
The processes initiated by collision of the antihydrogen ice with solid matter are considered. It is shown that such a collision will result in the fast annihilation of at least several tens percent of the antihydrogen even if the collision velocity is low. It is also shown that the cross-sections for capture of the antiprotons with the kinetic energies of the order of 0.1 MeV and greater by the atoms of the high-Z elements are much greater than those for capture of such antiprotons by atoms of the low-Z elements. The relatively high probability of annihilation of the antiprotons on the nuclei of the high-Z element(s) will determine both the parameters of the annihilation products, arising due to the possible accidents of several kinds, and the efficiency of several scenarios of the use of antimatter.
