Slowing YbF molecules using radiation pressure
M. Athanasakis-Kaklamanakis, G. Peng, S. Li +7
We report radiation pressure slowing of YbF molecules to low velocity. In YbF, laser slowing is hindered by leaks out of the optical cycle attributed to low-lying metastable electr…
Slow molecular beams from a cryogenic buffer gas source
A. D. White, S. Popa, J. Mellado-Munoz +4
We study the properties of a cryogenic buffer gas source that uses a low temperature two-stage buffer gas cell to produce very slow beams of ytterbium monofluoride molecules. The m…
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…
Understanding inner-shell excitations in molecules through spectroscopy of the 4f hole states of YbF
S. Popa, S. Schaller, A. Fielicke +4
Molecules containing a lanthanide atom have sets of electronic states arising from excitation of an inner-shell electron. These states have received little attention, but are thoug…
