Abstract

The radiative lifetime of the 𝐴 2 Π 1/2 (𝑣=0) state in radium monofluoride (RaF) is measured to be 35(1) ns. The lifetime of this state and the related decay rate Γ=2.86⁢(8)×107 s−1 are of relevance to the laser cooling of RaF via the optically closed 𝐴 2 Π 1/2 ←𝑋 2 Σ 1/2 transition, which makes the molecule a promising probe to search for new physics. RaF is found to have a comparable photon-scattering rate to homoelectronic laser-coolable molecules. Owing to its highly diagonal Franck-Condon matrix, it is expected to scatter an order of magnitude more photons than other molecules when using just three cooling lasers, before it decays to a dark state. The lifetime measurement in RaF is benchmarked by measuring the lifetime of the 8⁢𝑃3/2 state in Fr to be 83(3) ns, in agreement with literature.
