Abstract: We report spectroscopic and time-resolved experimental observations to characterize the [ Xe ] 4 f 13 ( F 5 / 2 o 2 ) 5 d 6 s ( D 1 ) 1 [ 5 / 2 ] 5 / 2 o state in Yb + 172 ions. We access this state from the metastable 4 f 14 5 d ( D 3 / 2 , 5 / 2 2 ) manifold and observe an unexpectedly long lifetime of τ = 37.9 ( 9 ) µ s that allows visible Rabi oscillations and resolved-sideband spectroscopy. Using a combination of coherent population dynamics, high-fidelity detection and heralded state preparation, and optical pumping methods, we measure the branching ratios to the D 3 / 2 2 , D 5 / 2 2 , and S 1 / 2 2 states to be 0.359 ( 2 ) , 0.639(2), and 0.0023 ( 16 ) , respectively. The branching ratio to the 4 f 13 6 s 2 ( F 2 7 / 2 ) is compatible with zero within our experimental resolution. We also report measurements of Landé g -factor of the 1 [ 5
