Abstract
Subject headings
Close
- We report on the first experimental observation of a new threshold behavior observed in the 5 2G partial channel in photodetachment of K-. It arises from the repulsive polarization interaction between the detached electron and the residual K(5 2G) atom, which has a large negative dipole polarizability. In order to account for the observation in the K(5 2G) channel, we have developed a semiclassical model that predicts an exponential energy dependence for the cross section. The measurements were made with collinear laser-ion beams and a resonance ionization detection scheme.
