Measurements of spontaneous-emission rates in atomic thallium

We report measurements of the following spontaneous-emission rates in atomic thallium: $A(6{D}_{\frac{3}{2}}\ensuremath{-}7{P}_{\frac{1}{2}})=(5.97\ifmmode\pm\else\textpm\fi{}0.78)\ifmmode\times\else\texttimes\fi{}{10}^{5}{\mathrm{s}}^{\ensuremath{-}1}$, $A(7{P}_{\frac{1}{2}}\ensuremath{-}7{S}_{\frac{1}{2}})=(1.71\ifmmode\pm\else\textpm\fi{}0.07)\ifmmode\times\else\texttimes\fi{}{10}^{7}{\mathrm{s}}^{\ensuremath{-}1}$, $A(7{P}_{\frac{3}{2}}\ensuremath{-}7{S}_{\frac{1}{2}})=(2.37\ifmmode\pm\else\textpm\fi{}0.09)\ifmmode\times\else\texttimes\fi{}{10}^{7}{\mathrm{s}}^{\ensuremath{-}1}$, and $A(8{P}_{\frac{3}{2}}\ensuremath{\rightarrow}\mathrm{all})=(9.2\ifmmode\pm\else\textpm\fi{}1.0)\ifmmode\times\else\texttimes\fi{}{10}^{6}{\mathrm{s}}^{\ensuremath{-}1}$. These results are compared to predictions of theoretical models and lend support to calculations of the recently measured parity-nonconserving circular dichroism of the $6{P}_{\frac{1}{2}}\ensuremath{-}7{P}_{\frac{1}{2}}$ forbidden $M1$ transition in thallium.
