Abstract

We report measurements of the branching fraction, hyperfine constant, and second-order Zeeman coefficient of the D5/2 level in 171Yb^+ with up to two orders-of-magnitude improvement in precision compared to previously reported values. We estimate the electric quadrupole reduced matrix element of the S1/2 leftrightarrow D5/2 transition to be 12.5(4) e a02. Furthermore, we determine the transition frequency of the F7/2 leftrightarrow 1D[3/2]3/2 at 760 nm with a sim25-fold improvement in precision. These measurements provide benchmarks for quantum-many-body atomic-physics calculations and provide valuable data for efforts to improve quantum information processors based on Yb^+.
