Study of Energy Levels and Decay Mechanisms for Singlet Rydberg States of Molecular Nitrogen.
Abstract
This report summarizes a series of investigations of the singlet Rydberg states of molecular nitrogen. The object of the research was to use laser excitation out of the metastable state of N2 to study the energy levels and decay mechanisms for the high lying singlet Rydberg and valence states. Two techniques were used to produce molecules in the metastable state -- electron excitation of N2 molecules in a thermal beam and charge capture by a fast beam of N2 ions. The first section summarizes the current knowledge of these states. The second section describes the measurements of the energy levels and lifetimes for individual notational levels. The third section describes the measurements of the lifetime of the metastable level which used a uv spectrometer and a pulsed electron beam. The fourth section summarizes a number of experiments which were not successful.
