Abstract
Some experimental limits on the annihilation cross sections sigma(ann) of antiprotons on carbon, palladium, and platinum targets were determined at the previously unexplored kinetic energy region E approximate to 125 keV. Information on sigma(ann) at such low antiproton energies is important in understanding the dynamics of the annihilation process, and provides useful data for models that attempt to describe the matter-antimatter asymmetry in the universe by assuming the existence of islands of antimatter concentration. © 2021 Elsevier B.V.
