Measurements of electric quadrupole transition frequencies in ${}^{226}$Ra${}^{+}$

Abstract

We report the first driving of the $7s{}^2{S}_{1/2}\to 6d{}^2{D}_{3/2}$ and $7s{}^2{S}_{1/2}\to 6d{}^2{D}_{5/2}$ electric quadrupole (E2) transitions in Ra${}^{+}$. We measure the frequencies of both E2 transitions, and two other low-lying transitions in ${}^{226}$Ra${}^{+}$ that are important for controlling the radium ion's motional and internal states: $6d{}^2{D}_{3/2}\to 7p{}^2{P}_{3/2}^0$ and $6d{}^2{D}_{5/2}\to 7p{}^2{P}_{3/2}^0$.
