We have developed a vapor cell and heater for an experiment to search for an electric dipole moment (EDM) of the electron using the metastable state a(1)[3Sigma+] of lead monoxide. Using our apparatus and the method of quantum beat spectroscopy, we have measured the g-factors of the a(1)(3Sigma+) state. We obtain (g&par;)- = 1.8571 +/- 0.0041 for the J = 1- component and ( g&par;)+ = 1.8584 +/- 0.0045 for the J = 1+ component. We also establish a limit on the difference of the g-factors of dgg=2&dot; g&dvbm0;- -g&dvbm0;+ g&par;-+ g&par;+ < 2.3 · 10-3 (90% CL). In the course of our measurements, we have demonstrated shot-noise limited sensitivity to the Zeeman quantum beat frequency of 35HzHz . We point out relatively straightforward improvements, which should increase the statistical sensitivity to 100mHzHz in the near future. With this level of sensitivity, it should be possible to measure an electron EDM of de =10-29 e · cm in less than two days.Subjects--Topical Terms:

520 $a In a separate set of experiments, we have searched for electronic states with a strong coupling to both the ground state and the a(1)[3Sigma +] state, which could be used to improve the excitation and detection efficiency in a future EDM experiment. To this end, we have measured radiative lifetimes and branching ratios for decay through the a(1)[3Sigma +] state for most known states of PbO.
