Time-of-Flight Spectroscopy of Ionic and Metastable Fragments from Dissociating Molecules.
Abstract
Progress is reported on research in molecular physics involving electron-bombardment molecular dissociation. The velocity distribution of metastable and ionic fragments are measured using a pulsed electron beam and a time-of-flight technique. During the past year, experiments involving detection of ionic fragments from the hydrogen halides and acytelene have been underway. The velocity spectrum of protons resulting from dissociation of the hydrogen halides show several distinct features, and attempts are presently being made to assign these features to particular molecular states. Measurements to determine electron bombardment threshold energies for these features have been made and should help in confirming such assignments. Several different ionic fragments have been detected from the dissociation of acytelene. A mass filter is used in these experiments to obtain velocity spectra of each mass species separately.
