A correlated continuum electron pair may have the ability to distinguish a right-handed coordinate frame from a left-handed one. This chirality may be produced (1) by double photoionization using circularly polarized light, or (2) by electron impact ionization of an oriented target where orientation is provided, for instance, by circularly polarized laser excitation. In both situations the coincidence detection of the electron pair shows under suitable kinematical conditions a circular dichroism, i.e. the two-electron angular correlations are different for right and left circular light polarizations. We present numerical results for double photoionization of He and H, and for the (e, 2e) reaction of oriented H(2p;m). The calculations show that the amount of dichroism depends strongly on the choice of used wave functions, particularly on the description of final state three-body continuum correlations, and on the energy distribution of the escaping electrons.
