Ionization potential of radium monofluoride
This paper reports the experimental measurement and relativistic coupled-cluster theoretical prediction of the ionization potential of radium monofluoride (RaF) as 4.969 eV, alongside an improved calculation of its dissociation energy, confirming that RaF is a unique diatomic molecule where the dissociation energy exceeds the ionization potential.
