Energies and lifetimes of the 9p and 10p excited states in atomic francium
P. Lassègues, A. Ajayakumar, M. Athanasakis-Kaklamanakis +29
We present the first measurement of 9p 2P1/2,3/2 and 10p 2P1/2,3/2 excited levels absolute wavenumbers and radiative lifetime in francium. We used the Collinear Resonance Ionizatio…

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…

Radiative lifetime of the A 2Î 1/2 state in RaF with relevance to laser cooling
M. Athanasakis-Kaklamanakis, S. G. Wilkins, P. Lassègues +38
The radiative lifetime of the (v=0) state in radium monofluoride (RaF) is measured to be 35(1) ns. The lifetime of this state and the related decay rate $Î= 2.86…
