Antiproton-impact ionization of Ne, Ar, Kr, Xe, and H2O
We calculate antiproton-impact total single ionization of Ne, Ar, Kr, Xe, and H2O using a time-dependent convergent close-coupling approach. The Ne, Ar, Kr, and Xe atom wave functions are described in a model of six p-shell electrons above a frozen Hartree-Fock core with only one-electron excitation...

| description | We calculate antiproton-impact total single ionization of Ne, Ar, Kr, Xe, and H2O using a time-dependent convergent close-coupling approach. The Ne, Ar, Kr, and Xe atom wave functions are described in a model of six p-shell electrons above a frozen Hartree-Fock core with only one-electron excitations from the outer p shell allowed. For treating the water molecule we use a neonization method recently proposed by Montanari and Miraglia [J. Phys. B: At. Mol. Opt. Phys. 47, 015201 (2014)], which describes the ten-electron water molecule as a dressed Ne-like atom in a pseudospherical potential. In the present work the target states of noble gas atoms and water are obtained using a Laguerre basis expansion. For the noble gas atoms there is reasonably good agreement with the calculated single-ionization cross sections. |
