Time-of-flight spectroscopy of ionic and metastable fragments from dissociating molecules
Abstract
This research involved the dissociation of hydrogen-containing molecules by electron impact and the subsequent measurement of the velocity of proton or metastable hydrogen fragments using time-of-flight methods. The proton velocity distribution resulting from dissociation of the hydrogen halides resulted in information on excited states of the corresponding molecular ions with inner-shell electron holes. Another completed project involved the proton velocity distribution from electron bombardment of the triatomic molecules, water and hydrogen sulfide. A final experiment involved the detection, in coincidence, of proton and metastable hydrogen fragments from electron bombardment of hydrogen molecules.
