Abstract:

The main objective of this project is a first exploration of a process not heretofore studied systematically, the detachment of electrons from negative ions when the ions collide with electronically excited neutral atoms or molecules. A steppingstone experiment, the two-color, two-photon photodetachment of the electrons from negative ions, is a part of the project as it is now being done. This report describes the completion of the apparatus for the steppingstone experiment and the first photodetachment results, and outlines precisely what the goals for the next few months will be, based on the success of the ion source and the laser. The steppingstone experiment is being conducted with Cl- ions to determine the dependence of the detachment probability on the total energy and the difference in energies of the two photons when this is complete, the ion optics and target cell for the collisional detachment experiment will be completed while the photodetachment work is extended to the study of the CN- ion.
