Abstract
The aim of this work is to give a simple and precise theoretical formalism to study the single ionization of small molecular targets by swift proton impact. The mathematical formalism given here for the sake to calculate the differential cross sections is based on the first-Born approximation using the Coulomb wave function. The incident and scattered continuum states of the proton are described by plane wave functions, and the ejected electron is described by a Coulomb wave function. The formalism under consideration is applied to study the single ionization of methane molecule. The comparison between our results and the experimental data showed good agreement.
