А method for evaluating the matrix element of an electric dipole transition between the states of the continuous spectrum with regard to the existence of an atom of Coulomb and polarization potentials in the exterior region has been considered. Recurrent formulas for evaluating the contribution of the integral over the domain outside the atom to the matrix element with the use of the values of the radial wave functions and their first derivatives on the boundary have been obtained.
