Hyperfine-mediated effects in a Lu optical clock
Zhiqiang Zhang, K. J. Arnold, R. Kaewuam +2
We consider hyperfine-mediated effects for clock transitions in Lu. Mixing of fine structure levels due to the hyperfine interaction bring about modifications to Landé…
Branching fractions for decays in Ba
Zhiqiang Zhang, K. J. Arnold, S. R. Chanu +3
Branching fractions for decays from the level in Ba have been measured with a single laser-cooled ion. Decay probabilities to , and $D_{5/2…
Suppressing inhomogeneous broadening in a lutetium multi-ion optical clock
Ting Rei Tan, Rattakorn Kaewuam, Kyle J. Arnold +4
We demonstrate precision measurement and control of inhomogeneous broadening in a multi-ion clock consisting of three Lu ions. Microwave spectroscopy between hyperfine…
Measurements of the branching ratios for decays in Ba
K. J. Arnold, S. R. Chanu, R. Kaewuam +5
Measurement of the branching ratios for decays to and in Ba are reported with the decay probability from to measu…
Oscillating quadrupole effects in high precision metrology
Kyle J. Arnold, R. Kaewuan, T. R. Tan +1
The influence of oscillating quadrupole fields on atomic energy levels is examined theoretically and general expressions for the quadrupole matrix elements are given. The results a…
