Experimental Evidence that the 6s6p 3PJ States of Cs- Are Shape Resonances
Abstract
An experimental study of the previously unobserved and controversial Cs-(6s6p PJo3) states has been conducted using a combination of infrared laser and storage ring experiments. This first application of photodetachment spectroscopy to the study of low-lying resonances in atomic negative ions has resulted in the observation of a narrow resonance structure, lying only 8.0(3) meV above the first detachment threshold of Cs-. The storage ring …
