In-gas-jet laser spectroscopy of No 254 with JetRIS
Résumé
Here we report online results with the in-gas-Jet Resonance Ionization Spectroscopy (JetRIS) apparatus. The S 0 1 ↔ P 1 1 transition of No 254 was successfully measured with sub-GHz resolution, marking a fivefold improvement over previous measurements. Recent developments in laser spectroscopy have allowed access to more exotic nuclei, but measurements of the heavy actinide region have been limited by line broadening mechanisms, limiting the precision with which nuclear properties can be deduced from the hyperfine spectrum. JetRIS provides a method to measure the heavy actinide region with a high level of sensitivity and higher resolution than previous experiments. The offline and online characterizations of the system are reported, and future perspectives are presented. Published by the American Physical Society 2024
