Measurement of the $7p{}^2{P}_{3/2}$ state branching fractions in ${\mathrm{Ra}}^{+}$

Abstract

We report a measurement of the radium ion's $7p{}^2{P}_{3/2}$ state branching fractions and improved theoretical calculations. With a single laser-cooled ${}^{226}{\mathrm{Ra}}^{+}$ ion we measure the $P_{3/2}$ branching fractions to the $7s{}^2{S}_{1/2}$ ground state 0.87678(20), the $6d{}^2{D}_{5/2}$ state 0.10759(10), and the $6d$ ${}^2{D}_{3/2}$ state 0.01563(21).
