Radiative Branching Ratios for Excited States of ${}^{174}$YbF: Application to Laser Cooling

I. J. Smallman, F. Wang, T. C. Steimle +2

We excite YbF molecules to low-lying vibrational levels of the $A^2{\Pi }_{1/2}$ state, and of the nearby perturber state sometimes called [18.6]0.5. By dispersing the fluorescence, we…
