Description

Partial photoionization cross sections and photoelectron angular distributions of He in the region of interfering Rydberg series below the n=5 threshold are measured and compared with theoretical results based 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
