Abstract

A new method for the calculation of the nonrelativistic amplitudes in a Coulomb field is proposed. The method is based on an operator representation of the Green function for a charged particle with a subsequent disentanglement of operator expressions. The dynamical algebra O (4,2) of the hydrogen atom is used. The calculation of the bremsstrahlung cross section is performed.
