Title:
A New Approach to Generating Negative Ion Beams.
Corporate Author:

Report Date:

Abstract:
The report describes measurements of ion-pair production cross sections for He21,3S-Li, Li-Cs, Li-Na, and Li-Na3p collisions at energies of several keV. Measurements of chemi-ionization cross sections for He21,3S-Li collisions are also mentioned. A method is described for exciting a fraction of the atoms in a Li vapor to the 2p resonance state using a dye laser. The fraction is determined by observing with the laser on and off the ion-pair production of Cl- when a fast Cl beam collides with the vapor. Keywords Ion pair production, Ionization, Cross sections, Molecular beams, Reaction rates.
