Abstract:

This project involved theoretical calculations of microscopic atomic and molecular processes in the generation of H- in a hydrogen plasma. Efficient production of H- is essential for practical applications such as particle beams and fusion plasmas. The specific objectives of the project were 1 to calculate cross sections foe dissociative recombination of electrons with H2 2 to provide theoretical analysis for ongoing experiments that use multiphoton ionization to investigate the spectroscopy of excited states of molecular hydrogen, and 3 to calculate cross sections for dissociative attachment of electrons with vibrationally excited hydrogen molecules.
