Ionization potential of radium monofluoride
S. G. Wilkins, H. A. Perrett, S. M. Udrescu +43
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. T…
Observation of the distribution of nuclear magnetization in a molecule
S. G. Wilkins, S. M. Udrescu, M. Athanasakis-Kaklamanakis +33
Rapid progress in the experimental control and interrogation of molecules, combined with developments in precise calculations of their structure, are enabling new opportunities in…
Accurate theoretical determination of the ionization potentials of CaF, SrF, and BaF
A. A. Kyuberis, L. F. Pasteka, E. Eliav +6
We present a comprehensive theoretical study of the ionization potentials of the MF (M= Ca, Sr, Ba) molecules using the state-of-the-art relativistic coupled cluster approach with…
Pinning down electron correlations in RaF via spectroscopy of excited states and high-accuracy relativistic quantum chemistry
M. Athanasakis-Kaklamanakis, S. G. Wilkins, L. V. Skripnikov +53
We report the spectroscopy of the 14 lowest excited electronic states in the radioactive molecule radium monofluoride (RaF). The observed excitation energies are compared with full…
