Laser spectroscopy and CP-violation sensitivity of actinium monofluoride
M. Athanasakis-Kaklamanakis, M. Au, A. Kyuberis +39
The apparent invariance of the strong nuclear force under combined charge conjugation and parity (CP) remains an open question in modern physics. Precision experiments with heavy a…
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…
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…
King-plot analysis of isotope shifts in simple diatomic molecules
Michail Athanasakis-Kaklamanakis, Shane G. Wilkins, Alexander A. Breier +1
We demonstrate that the isotope shift in isotopomers of diatomic molecules, where the nucleus of one of its constituent atoms is replaced by another isotope, can be expressed as th…
The Rotationally Resolved Infrared Spectrum of TiO and Its Isotopologues
Daniel Witsch, Alexander A. Breier, Eileen Döring +3
In this study, we present the ro-vibrationally resolved gas-phase spectrum of the diatomic molecule TiO around 1000\,cm. Molecules were produced in a laser ablation source b…
