Selective Final-State Population in Electron Capture by Low-Energy Highly Charged Projectiles Studied by Energy-Gain Spectroscopy

Abstract
Energy-gain spectra and total cross sections have been measured for projectiles of 492-eV Ne+10 and 443-eV Ne+9 capturing electrons from rare-gas targets. For each collision system a single, or at most two, principal quantum numbers on the projectile are found to be populated. The effective electron-transfer probabilities are found to be quite dependent upon the collision system.
