Outline of Final Research Achievements

We showed theoretically that electron correlation can break the symmetry of photoelectron angular distributions upon a two-step ionization to doubly degenerate ion via doubly degenerate intermediate states of molecules in isotropic ensemble. The symmetry breaking is ascribed to the interference effects of different types of electronic configurations. These effects would be useful for experimental characterization of many-electron wave functions.
