Hyperfine transition in ²⁰⁹Bi⁸⁰⁺ — one step forward
Phys. Scripta, 2015 :014021 (November 2015)
Abstract:
The hyperfine transitions in lithium-like and hydrogen-like bismuth were remeasured by direct laser spectroscopy at the experimental storage ring. For this we have now employed a voltage divider which enabled us to monitor the electron cooler voltage in situ . This will improve the experimental accuracy by about one order of magnitude with respect to our previous measurement using the same technique.
