Spectroscopic study of the 7p1/2 and 7p3/2 states in cesium-133

Doppler free spectroscopy was performed on the 7p1/2 and 7p3/2 states in neutral cesium-133 using a frequency doubled titanium sapphire laser stabilized to a temperature-stabilized ultra-low expansion optical cavity. The absolute frequencies for the centers of gravity of the two states were determined to be cm−1 and cm−1, factors of 500 and 650 better than previously reported measurements, respectively. The magnetic dipole and electric quadrupole constants were measured to be MHz for the 7p1/2 state and MHz and MHz for the 7p3/2 state, which are consistent with previously published values.
