Vacuum Ultraviolet Spectroscopy of H- in a Heavy Ion Storage Ring: The Region near the H(n=2) Threshold
Abstract
The negative hydrogen ion has been investigated by a new spectroscopic approach in the region near the n=2 threshold of the neutral hydrogen atom. The technique is based on Doppler-tuned spectroscopy using an H- beam stored in a heavy ion storage ring collinearly overlapped with a fixed-frequency narrow-bandwidth vacuum ultraviolet laser beam (118 nm). The position of the Feshbach resonance is determined as 10.9243(3) eV which is in good …
