We explore from a theoretical perspective angular distributions of electrons emitted from a Na8 cluster after excitation by a short laser pulse. The tool of the study is time-dependent density-functional theory (TDDFT) at the level of the local-density approximation (LDA) augmented by a self-interaction correction (SIC) to put emission properties in order. We consider free Na8 and Na8 deposited on the surfaces MgO(001) or Ar(001). For the case of free Na8, we distinguish between a hypothetical situation of known cluster orientation and a more realistic ensemble of orientations. We also consider the angular distributions for emission from separate single-electron levels.
