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…

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…
