Abstract
Energy- and angle-resolved triply differential cross sections have been mea sured in the double photoionization of helium under equal and unequal energ y sharing conditions using right- and left-elliptically polarized photons. Linear dichroism in these cross sections has been observed under the equal energy sharing. For the unequal energy sharing a pure circular polarization effect has been deduced by eliminating the linear polarization contributio n.
