SPH: Atomic angular mometum polarization

Vector correlations in photodissociation processes provide deep insight into dissociation dynamics. The name “SPH” is the abbreviation for Spin Polarized Hydrogen which we showed we could probe directly using a variant of the Rydberg tagging technique. This instrument, built by Bernadette Broderick at Wayne State, is capable both of Rydberg tagging and high resolution slice imaging.This work is supported by the National Science Foundation.
