Under certain conditions specified in this work, a two-particle orbital orientation of bound states can be detected by means of double photoemission with polarized light. These conclusions are based on a tensorial analysis of the dipole transition amplitudes and are illustrated by a numerical study of double photoemission from helium oriented by laser-pumping. The analytical and numerical results demonstrate the interrelation between two-particle correlation and orbital polarization.
