Statistics and systematics of electron EDM searches with BaF
A. Boeschoten, V. R. Marshall, T. B. Meijknecht +26
The NL-EDM experiment searches for a non-zero electric dipole moment of the electron (EDM) in the ground state of barium monofluoride (BaF). A beam of BaF from a supers…
A sub-ppm upper limit on the cosmological variations of the fine structure constant alpha
S. Muller, A. Beelen, M. Guelin +9
Absorption spectroscopy toward high-redshift quasars provides strong constraints on the putative variation of fundamental constants of physics on cosmological time scales. The subm…
Precision spectroscopy of the transition in BaF
M. C. Mooij, H. L. Bethlem, W. Ubachs +14
High-resolution spectroscopy on the - electronic system of BaF is performed using a cold molecular beam produced by a buffer gas source. The hyperf…
2D transverse laser cooling of a hexapole focused beam of cold BaF molecules
Joost W. F. van Hofslot, Izabella E. Thompson, Anno Touwen +18
A cryogenic buffer gas beam, an electrostatic hexapole lens, and 2D transverse Doppler laser cooling are combined to produce a bright beam of barium monofluoride (Ba…
