The classical trajectory Monte Carlo simulation has been used to investigate the collisions
of protons with alkali metal atoms in their ground state. Model interaction potential has
been used to describe the electron-ionic core interaction. The cross sections for the
capture and ionization in the energy range 1–100 keV/amu have been calculated and
compared with the available experimental and theoretical results. The effects of the
presence of a strong static electric field in different geometrical features on the capture
and ionrzation cross sections have also been investigated. It has been found that the
electric field causes the cross section for the capture to decrease while for the ionization
enhance dramatically. Many of the null field features are retained. The analyses of the final
state n, l-distribution in the electron capture process reveals H(2p) to be the most
populated level in both the cases, with and without electric field.
