| Popis: | Electron loss in proton-water collisions is studied in the energy range 100 keV < E < 1 MeV by employing a three-center model potential. The electron-loss probabilities are calculated by applying a new lattice method that yields cross sections which are in good agreement with previous semiclassical close-coupling and classical calculations. The lattice method also provides a straightforward visualization of the ionization mechanism at high impact velocities that involves a quasi-free expansion of the electron cloud This work has been partially supported by projects ENE2011-28200 and ENE2014-52432-R of the Secretaría de Estado de I+D+i (Spain). Calculations have been performed at the Centro de Computación Científica (UAM, Madrid) and partly at the Barcelona Supercomputing Center (BSC) with financial support from the Red Española de Supercomputación (RES; grants FI-2012-2-0016, FI-2013-1-0020 and FI2013-2-0006) |
