Coincidence detection of protons and metastable hydrogen atoms from dissociative ionization of molecular hydrogen by electron impact

Thesis/Dissertation ·
OSTI ID:5938414
A coincidence was observed between H(2S) and H/sup +/ fragments resulting from the bombardment of H/sub 2/ with 100-eV electrons. A significant source of this coincidence is believed to be the 2ssigma/sub g/ state of H/sub 2//sup +/. The time-of-flight (TOF) distribution of H(2S) fragments from the 2ssigma/sub g/ state was measured and converted to the kinetic energy distribution from which the potential energy of the 2ssigma/sub g/ state in the Franck-Condon region was constructed. The result is in good agreement with a published calculation.
