Precision Isotope-Shift Measurement of the Transition and a Multi-Transition King-Plot Consistency Test
Taiki Ishiyama, Koki Ono, Reiji Asano +6
We present precision spectroscopy and isotope shift measurement of the clock transition in neutral ytterbium () atoms. By revealing a…
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 in neutral ytterbium atoms has attracted much attention as a new optical frequency standard a…
Observation of an Inner-Shell Orbital Clock Transition in Neutral Ytterbium Atoms
Taiki Ishiyama, Koki Ono, Tetsushi Takano +2
We observe a weakly allowed optical transition of atomic ytterbium from the ground state to the metastable state for all five bosonic and two fermionic iso…
Observation of non-linearity of generalized King plot in the search for new boson
Koki Ono, Yugo Saito, Taiki Ishiyama +6
We measure isotope shifts for neutral Yb isotopes on an ultranarrow optical clock transition with an accuracy of a few Hz. The part-per-billion…
