Abstract : It is shown that the use of the dipole acceleration form of the photoionization cross section in a high-energy Born expansion gains one iteration of the Born series over the corresponding expansion of the dipole-velocity cross section. Some comparisons with Hartree-Fock indicate the domain of validity of the acceleration Born approximation. (Author)
