In previous work, the eigenchannel R-matrix method was extended to calculate the double photoionization of helium by single-photon absorption for photon energies in the range 80-280 eV. Calculations were performed in both the velocity and acceleration gauges. A significant discrepancy ({approx} 20%) was found between the two gauge results. The relationships between the various gauge forms are discussed. In an effort to resolve the discrepancy between the gauges, alternate methods are explored.
