Studies of Barium Excitation by Molecular Beam Magnetic Resonance Techniques.

Abstract

A laboratory program to investigate photoionization of the singlet D and triplet D barium metastable states has been in progress. The effort involves the generation of an intense beam of the atomic barium metastable states, development of instrumentation for beam detection, and determination of oscillator strengths for photon excited transitions to the barium autoionizing states. Experimental results to date rely on the Majorana effect to measure the overall barium metastable population changes. Beam irradiation experiments have measured metastable depopulation for radiation over the 2300A to 3400A band and a population increase for radiation over a 2300A to 15,000A band. Further, no population change is observed for irradiation over a 3000A to 15,000A band. (Author)
