Polarization of Pb Vapor. I. Orientation of theP03Ground State ofPb207

Abstract

The method of optical pumping of diamagnetic atoms with zero orbital angular momentum (${}_{}{}^1{}_{}{}^{}S_0^{}{}_{}{}^{}$) has been extended to an atom with nonzero orbital angular momentum (${}_{}{}^3{}_{}{}^{}P_0^{}{}_{}{}^{}$), yielding ${\left|{\mu }_I\right|}_{\mathrm{uncorrected}}=0.5726\mathrm{}\left(6\right)\mathrm{} {\mu }_N$. An expression for the signal is found and the complications of branching to the metastables are discussed. The appratus is described.
