    "abstract": "In this article we present triple differential cross sections for equal\nenergy sharing kinematics for double photoionization of the helium atom at 20\nand 40eV above threshold in the framework of the hyperspherical partial wave\ntheory. This supplements our earlier work \\cite{DCP03} in which we were\nsuccessful in showing fully, gauge independence of the results in our\nformalism. Also in this work we treat cases in which the Stokes parameter S$_1\n\u003c 1$ so that partial polarization of the photon source is also taken into\naccount. Agreement in shape with the Convergent Close Coupling \\cite{BK03,HB98}\ncalculation and the experiments appears to be excellent.",
