Progress towards a Nuclear Anapole Moment Measurement in $^{137}$BaF.

We report progress in our experiment to measure nuclear spin- dependent parity violating effects. Our first goal is to measure the nuclear anapole moment of $^{137}$BaF. We have developed an intense, cold beam of BaF molecules by laser ablation and supersonic expansion. This beam is injected into a homogeneous 0.5 T magnetic field. The field is measured and shimmed with an array of custom broadband NMR probes and commercial room-temperature shim array. We have observed Stark-induced transfer between two Zeeman-rotational sublevels of $^{138}$BaF as a function of magnetic field, indicative of the Zeeman-tuned level crossing of these two states. A similar level-crossing in $^{137}$BaF will be used to amplify the effect of the nuclear anapole moment to an observable level.
