Probing the electroweak structure of nuclei with rare atoms and molecules
Silviu-Marian Udrescu, Antoine Belley, Jason D. Holt +2
Precision experiments of atoms and molecules have become a powerful probe of the electroweak structure of atomic nuclei and of physics beyond the Standard Model. We review how the…
Non-destructive cavity readout of molecules for precision measurements
Alejandro Salas-Estrada, Silviu-Marian Udrescu, Geoffrey Zheng +6
We propose a non-destructive method to measure the population of molecules in a selected rotational-hyperfine state by coupling them to a high-finesse optical cavity. In contrast t…
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…
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…
