Lifetime of the ${}^2{F}_{7/2}$ level in Yb${}^{+}$ for spontaneous emission of electric octupole radiation

R. Lange, A. A. Peshkov, N. Huntemann +3

We report a measurement of the radiative lifetime of the ${}^2{F}_{7/2}$ level of ${}^{171}$Yb${}^{+}$ that is coupled to the ${}^2{S}_{1/2}$ ground state via an electric octupole transition. Th…
