Nuclear-Electron Versus Nuclear-Nuclear Interactions in Ionization of Atoms by Highly Charged Ions Impact
Abstract
The correlated behavior of the electron and recoil-nucleus ion is studied for atomic ionization by collisions with fast, highly charged ions. Calculations were performed using classical-Trajectory Monte Carlo and quantum-mechanical Continuum Distorted Wave methods that incorporate all interactions including the internuclear potential. Electron double and triple differential ionization cross sections are presented as a function of projectile momentum transfer for hydrogen ionization by 3.6 MeV/u Au53+ impact. It is possible to identify collision mechanisms that give rise to binary-like peak electrons, and a new class of electrons recently predicted for highly charged ions impact, which were termed "swing by electrons". the relative importance of each mechanism is determined by the range of the nuclear-nuclear versus that of the nuclear-electron interactions. an experimentally accessible method for the separation of these different mechanisms based on the study of the azimuthal angle of the particles is proposed.
