Time-offlight Spectroscopy of Molecular Structure, Collision Processes, and Gas-Surface Interactions.

Abstract

Progress in molecular physics research using time-of-flight techniques to measure velocity distributions of fragments from dissociating molecules is reported. Electron bombardment at energies between 20 and 100 eV was used to dissociate the molecules, and only fragments with kinetic energies greater than about 1 eV were detected. Both metastable hydrogen atoms and one-, two-, and three-atom hydrogenic charged fragments were detected. Special selective detectors were designed and built for metastable hydrogen atoms as well as a mass filter for identifying the mass of ionic fragments. A large portion of this work was done using the hydrogen molecule and its deuterated forms; however, heavier molecules such as methane, ethane, methanol, and ethanol, were also studied. (Author)
