Overview

Spectroscopic experiment reveals an ultraprecise Landé g-factor for the 2D3/2 state in ytterbium-171 ions, highlighting improved accuracy for next-generation optical clocks.

Key Points

  • To precisely measure the Landé g-factor and hyperfine splitting of the 2D3/2 state in 171Yb+ to improve optical clock evaluations and tests of fundamental physics.
  • Confined 171Yb+ ions in a linear Paul trap.
  • Performed microwave spectroscopy on hyperfine transitions across the 2S1/2 and 2D3/2 state manifolds.
  • Determined the Landé g-factor ratio gF,D/gF,S to be 0.998060(5), yielding g(D3/2) = 0.79917(3) with an order-of-magnitude improvement in precision over prior measurements.
  • Measured the 2D3/2 hyperfine splitting WD3/2 to be 857,178,077(3) Hz, consistent with existing values.
