The quantum molecular dynamics method was applied to a simple system composed of an electron, ions and surface molecules in order to investigate an energy transfer process to a thermo or secondary electron in surface collision process of an ion or an atom. A time dependent Schrodinger equation for a thermo or secondary electron was solved by the splitting operator method and Newton's equations for ions and surface molecules were solved by the molecular dynamics method. With the increase of interaction between the observed electron and the colliding ion the energy transfer to the electron during ionic collision process increased. Energy transfer to the observed electron through the potential energy term between the colliding ion and the observed electron and through the potential energy term between the surface molecules and the observed electron were dependent on the colliding energy of an ion.
