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…

Cr as a Doorway to the N = 40 Island of Inversion

L. Lalanne, M. Athanasakis-Kaklamanakis, D. D. Dao +24

This paper reports on the measurement of the ground-state spin and nuclear magnetic dipole moment of Cr. The radioactive ion beam was produced at the CERN-ISOLDE facility an…

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…

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…

From classical to quantum loss of light coherence

Pierre Lassègues, Mateus Antônio Fernandes Biscassi, Martial Morisse +7

Light is a precious tool to probe matter, as it captures microscopic and macroscopic information on the system. We here report on the transition from a thermal (classical) to a spo…

Field and intensity correlations: the Siegert relation from stars to quantum emitters

Pierre Lassègues, Mateus Antônio Fernandes Biscassi, Martial Morisse +9

The Siegert relation relates field and intensity temporal correlations. After a historical review of the Siegert relation and the Hanbury Brown and Twiss effect, we discuss the val…
