An asymptotic expansion of the Whittaker function Mα,β(x), for β→∞, with α and x fixed, is employed to obtain the asymptotic expansion of the Dirac–Coulomb radial Green's function Gκ(x2,x1,z) when the magnitude of the angular momentum quantum number κ is large. This result has application in numerical calculations of quantum electrodynamic effects in an external Coulomb field. © 1995 American Institute of Physics.
