Microwave spectroscopy and multi-channel quantum defect analysis of ytterbium Rydberg states
Rin Kuroda, Vernon M. Hughes, Martin Poitrinal +2
The complex Rydberg structure of ytterbium atoms is shaped by multiple low-lying ion-core-excited states and strong channel interactions, which presents both opportunities and chal…
