Stopping power of molecules for fast ions

Abstract

The interaction of fast (tens of keV/amu) ions with atoms, molecules, and solids, has been a subject of interest to some in the Quantum Theory Project and their collaborators for some time, resulting in theoretical and computational investigations of various aspects of the problem. This note briefly reviews several broad areas that have received, and continue to receive attention.

Keywords:

• stopping power
• fast ions
• mean excitation energy
• collision cross sections
• electron nuclear dynamics
