Orders-of-magnitude improvement in precision spectroscopy of an inner-shell orbital clock transition in neutral ytterbium

Taiki Ishiyama, Koki Ono, Hokuto Kawase +6

An inner-shell orbital clock transition $^{1} S_{0} \leftrightarrow 4 f^{13} 5 d 6 s^{2} (J = 2)$ in neutral ytterbium atoms has attracted much attention as a new optical frequency standard a…

Excluding Hypothetical Light Boson Interpretation of Yb King Plot Nonlinearity with the $^{1} S_{0} \leftrightarrow^{3} P_{2}$ Isotope Shift Measurement

Taiki Ishiyama, Koki Ono, Reiji Asano +6

We present precision spectroscopy and isotope shift measurement of the $^{1} S_{0} \leftrightarrow^{3} P_{2}$ clock transition in neutral ytterbium ( $Yb$ ) atoms. By revealing a…
