Ionization in Time-Dependent Processes: Proton-Hydrogen Collisions

Part of the Physics of Atoms and Molecules book series (PAMO)


Measurements of the electron energy and angular distributions of emitted electrons are a widely-used probe of atomic dynamics. The COLd-Target-Recoil-Ion-Mass-Spectrometry (COLTRIMS) imaging technique has been used to obtain energy and angular distributions of electrons ejected from atoms in a variety of atomic processes1. Distributions of electrons produced by slow ion-atom collisions are of particular interest since there is as yet no consensus as to the physical mechanisms that transfer energy from heavy, charged ions with velocity v to electrons. The main difference between electron spectra at low and high-energy is a small contribution or absence of the binary encounter peak in the spectra at low-energy.
