We report the first measurements and associated theory for angular correlations of sequential cascading photons for an atomic system in which a scattering plane is defined. The cascade radiation from the n=3 levels of atomic hydrogen excited by 290 eV electrons is observed. The first determinations of a rank-4 multipole and of the magnetic sublevels of the 3d state have been made. The measured angular correlations and the deduced multipole moments have order-of-magnitude agreement with Glauber, Born, and six-state close-coupling model predictions.
