Velocity map imaging of a slow beam of ammonia molecules inside a quadrupole guide

Marina Quintero Pérez, Paul Jansen, Hendrick L. Bethlem

Velocity map imaging inside an electrostatic quadrupole guide is demonstrated. By switching the voltages that are applied to the rods, the quadrupole can be used for guiding Stark…

Sensitivity to a possible variation of the Proton-to-Electron Mass Ratio of Torsion-Wagging-Rotation Transitions in Methylamine (CH3NH2)

Vadim V. Ilyushin, Paul Jansen, Mikhail G. Kozlov +4

We determine the sensitivity to a possible variation of the proton-to-electron mass ratio μfor torsion-wagging-rotation transitions in the ground state of methylamine (CH3NH2). Our…
