Laser and microwave spectroscopy of even-parity Rydberg states of neutral ytterbium and Multichannel Quantum Defect Theory analysis

H. Lehec, A. Zuliani, W. Maineult +5

New measurements of high-lying even parity $6sns{}^1{S}_0$ and $6snd{}^{3,1}{D}_2$ levels of neutral ${}^{174}$Yb are presented in this paper. Spectroscopy is performed by a t…
