Fig. 9From: Optimal beam sources for Stark decelerators in collision experiments: a tutorial reviewExperimental REMPI spectrum of ND 3 molecules exiting the decelerator, probing exclusively the low-field seeking upper component of the inversion doublet for each rotational state. All lines in the spectrum originate from the upper inversion doublet component of the |J,K〉=|1,1〉 state. Population in other rotational states is negligibleBack to article page
