Metastable Negative Ions and Ion Pair Formation

Abstract

Experimental work was directed primarily toward determining properties (energies, lifetimes, autodetachment and photodetachment) of metastable autodetaching negative ions, including He2, Ca-, He-, and vibrationally detaching OH-. Also explored were the dissociative decay mechanisms and pathways of the lower Rydberg states of HeH, NeH, NeD, H3, D3, H2D, OH, and O2, using two translational spectroscopic methods. In addition, work was devoted to understanding the mechanisms that could control the behavior of Cs-seeded H- ion sources developed for high energy neutral beam production. Metastable negative ions, Rydberg states, Helium, Hydrogen, Neon, Hydroxide.
