Abstract
We present a semi-recursive method for calculating the rational parts of one-loop gravity amplitudes which utilises axial gauge diagrams to determine the nonfactorising pieces of the amplitude. This method is used to compute the amplitudes M 1-loop(1−, 2+, 3+, 4+, 5+) and M 1-loop(1−, 2+, 3+, 4+, 5+, 6+).
