| Popis: | We report time-correlated measurements of the lifetimes of the $7p{\phantom{\rule{0.222222em}{0ex}}}^{2}{P}_{3/2}$ and $7p{\phantom{\rule{0.222222em}{0ex}}}^{2}{P}_{1/2}$ states of atomic cesium. The results of these measurements are ${\ensuremath{\tau}}_{3/2}=137.54\phantom{\rule{4pt}{0ex}}(16)$ ns and ${\ensuremath{\tau}}_{1/2}=165.21\phantom{\rule{4pt}{0ex}}(19)$ ns. We use these lifetimes, together with other previously determined electric dipole matrix elements of $^{133}\mathrm{Cs}$, to determine the matrix elements $\ensuremath{\langle}5d{\phantom{\rule{0.16em}{0ex}}}^{2}{D}_{5/2}\ensuremath{\parallel}r\ensuremath{\parallel}7p{\phantom{\rule{0.16em}{0ex}}}^{2}{P}_{3/2}\ensuremath{\rangle}, \ensuremath{\langle}5d{\phantom{\rule{0.16em}{0ex}}}^{2}{D}_{3/2}\ensuremath{\parallel}r\ensuremath{\parallel}7p{\phantom{\rule{0.16em}{0ex}}}^{2}{P}_{3/2}\ensuremath{\rangle}$, and $\ensuremath{\langle}5d{\phantom{\rule{0.16em}{0ex}}}^{2}{D}_{3/2}\ensuremath{\parallel}r\ensuremath{\parallel}7p{\phantom{\rule{0.16em}{0ex}}}^{2}{P}_{1/2}\ensuremath{\rangle}$. These matrix elements are in good agreement with, but of higher precision than, calculated values of these same matrix elements. |
