We explore from a theoretical perspective angular distributions of electrons emitted from a Na 8 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 Na 8 and Na 8 deposited on the surfaces MgO(001) or Ar(001). For the case of free Na 8 , 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.
