Antiproton stopping power data for radiation therapy simulations

Stopping powers of H, He, H-2, and H2O targets for antiprotons have been calculated using a convergent close-coupling method. For He and H-2 targets electron-electron correlations are fully accounted for using a multiconfiguration approximation. Two-electron processes are included using an independent-event model. The water molecule is described using a neon-like structure model with a pseudo-spherical potential. Results are tabulated for the purpose of Monte Carlo simulations to model antiproton transport through matter for radiation therapy. (C) 2016 Associazione Italiana di Fisica Medica.
