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…
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…
Radiative lifetime of the A 2Π1/2 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 $Γ= 2.86(8…
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…
