Manipulating a beam of barium fluoride molecules using an electrostatic hexapole
Anno Touwen, Joost W. F. van Hofslot, Thijs Qualm +14
An electrostatic hexapole lens is used to manipulate the transverse properties of a beam of barium fluoride molecules from a cryogenic buffer gas source. The spatial distribution o…
A compact design for a magnetic synchrotron to store beams of hydrogen atoms
Aernout P P van der Poel, Katrin Dulitz, Timothy P Softley +1
We present a design for an atomic synchrotron consisting of 40 hybrid magnetic hexapole lenses arranged in a circle. We show that for realistic parameters, hydrogen atoms with a ve…
Constraints on changes in the proton-electron mass ratio using methanol lines
N. Kanekar, W. Ubachs, K. M. Menten +6
We report Karl G. Jansky Very Large Array (VLA) absorption spectroscopy in four methanol (CHOH) lines in the gravitational lens towards PKS1830-211. Three of the…
Preparation of an ultra-cold sample of ammonia molecules for precision measurements
Marina Quintero-Pérez, Thomas E. Wall, Steven Hoekstra +1
We present experiments in which an ultra-cold sample of ammonia molecules is released from an electrostatic trap and recaptured after a variable time. It is shown that, by performi…
Ramsey-type microwave spectroscopy on CO ()
A. J. de Nijs, W. Ubachs, H. L. Bethlem
Using a Ramsey-type setup, the lambda-doublet transition in the level of the state of CO was measured to be 394 064 870(10) Hz. In our molecular beam apparatus,…
