Theoretical Penning electron-energy distributions for alkali-metal atoms: He(2 /sup 1,3/S) collisions with sodium and potassium
Abstract
Penning electron-energy distributions are calculated for collisions ofHe(2 /sup 1/S) and He(2 /sup 3/S) with sodium and potassiumatoms. The formulation is in terms of quantum-mechanical wave functions, whichare determined using previously published complex potentials for the initialstates and available experimental or presently calculated Hartree-Fockpotential curves for the final state. Sensitivities to these potentials aretested. The mechanisms for the observed energy structure are analyzed, and theeffects of experimental finite energy resolution and collisional velocityspread on the structure are shown.
