Radio frequency spectroscopy measurement of the Landé g factor of the 5D5/2 state of Ba+ with a single trapped ion

Abstract

We report an improved measurement of the Landé g factor of the 5D5/2 state of singly ionized barium. Measurements were performed on single Doppler-cooled 138Ba+ ions in linear Paul traps using two similar, independent apparatuses. Transitions between Zeeman sublevels of the 6S1/2 and 5D5/2 states were driven with two independent, stabilized radio-frequency synthesizers using a dedicated electrode within each ion trap chamber. State detection within each Zeeman manifold was achieved with a frequency-stabilized fiber laser operating at 1.76 microns. By calculating the ratio of the two Zeeman splittings, and using the measured Landé g factor of the 6S1/2 state, we find a value of 1.200371(4stat)(6sys) for g of 5D5/2.
