Abstract

The fluorescence spectrum resulting from laser excitation of the A2Π1/2X2Σ+ (0,0) band of ytterbium monofluoride, YbF, has been recorded and analyzed to determine the Franck–Condon factors. The measured values are compared with those predicted from Rydberg–Klein–Rees (RKR) potential energy curves. From the fluorescence decay curve the radiative lifetime of the A2Π1/2 state is measured to be 28 ± 2 ns, and the corresponding transition dipole moment is 4.39 ± 0.16 D. The implications for laser cooling YbF are discussed.
