The primary aim of this project is to investigate the role played by the initial rovibrational excitation of a molecule in enhancing the cross sections and, therefore, the rates of dissociative electron attachment to the molecule. An enhancement of the attachment rate results in the enhancement of the production of negative-ion beams. The processes of dissociative electron attachment and of resonant vibrational excitation are complementary processes as the intermediate resonant-anion state of the molecule, formed by electron impact, either can autodetach the electron or can dissociate itself. Therefore, as a further part of the investigations excitation of the molecule was explored. The first project was to study the effect of initial vibrational excitation on the rates of production of negative atomic lithium ions via the process of dissociative electron attachment of lithium dimers.
