Ionization potential of radium monofluoride
Year: 2025
Type: article
Abstract: The ionization potential (IP) of radium monofluoride (RaF) was measured to be 4.969(2)[10] eV, revealing a relativistic enhancement in the series of alkaline earth monofluorides. The results are in agreement with a relativistic coupled-cluster prediction of 4.981(7) eV, incorporating up to quantum electrodynamics corrections. Using the same computational methodology, an improved calculation for the dissociation energy ( D 0 ) of 5.54(5) eV is presented. This confirms that RaF joins the group of diatomic molecules for which D 0 > IP , paving the way for precision control and interrogation of its Rydberg states.
