Observation of resolved Zeeman thresholds in photodetachment in a magnetic field

Abstract
Experiments on photodetachment from selenium negative ions in magnetic fields of 6.33 and 7.83 T have allowed the observation of photodetachment from resolved Zeeman levels for the first time. The measured relative detachment strengths for the Zeeman thresholds are not in agreement with the presently available theoretical prediction. Some possible sources of this disagreement are suggested.
