Abstract:

This report is intended to provide an update on the progress of an ongoing investigation into the recombination of electrons with hydrogenic molecular ions, namely, hydrogen 2, and hydrogen 3. Recombination is of major importance in determining the physical and chemical state of plasmas such as are found in hydrogen ion sources. Molecular ions are usually created with considerable internal energy in the form of vibrational and rotational excitation. Under this condition such ions generally exhibit large recombination rates and will represent a significant loss mechanism for low energy electrons in the discharge. These electrons are needed for attachment to vibrationally excited hydrogen 2 molecules in order to produce H.
