Abstract
Partial photoionization cross sections and photoelectron angular distr ibutions of He in the region of interfering Rydberg series below the n = 5 threshold are measured and compared with theoretical results base d on the hyperspherical close-coupling method. At a bandpass of 12 meV for the photon energy, this level of differentiation offers the most critical assessment of the dynamics of the two-electron excitations to date. A good understanding is achieved.
