Two-electron excitation in slow ion-atom collisions: Interference among autoionizing states
Abstract
Structures found in the Auger electron energy distribution that are due to interferences resulting from collisions of H{sup +} ions with He atoms below 5 keV are theoretically studied within a close-coupling scheme based on molecular representation. The present study identifies the dominant interference-related contributors to the structures. These contributors are due to the interferences between different autoionizing electronic states, incoming and outgoing parts of collisions on a single trajectory, different locations that have the same ejected electron energy on a single trajectory, and different trajectories. 7 refs., 2 figs.
