Abstract
An expression for the n-point one-loop graviton scattering amplitude with a singlenegative helicity external leg is constructed using an augmented recursion technique. We analyse the soft-limits ofthese amplitudes and demonstrate that they have soft behaviour beyond the conjectured universalbehaviou...
