Abstract

The angular distribution of photoelectron emission is explored from a theoretical perspective using time-dependent density-functional theory as a tool. We discuss the principal features of one- and two-photon processes for Na3+ with a simple jellium background. As more realistic test cases, we consider Na9+ and Na41+ with detailed ionic structure and compare the results with a jellium description. We find that high-frequency photons are required to resolve ionic details. Moreover, it is desirable to have simultaneously energy-resolved angular distributions to disentangle the details of the electronic structure.
