We present a very simple method for calculating the mixed Coulomb-nuclear effects in the pp and pp scattering amplitudes, and illustrate the method using simple models frequently used to describe their differential cross sections at small momentum transfers. Combined with the pure Coulomb and form-factor contributions to the scattering amplitude which are known analytically from prior work, and the unmixed nuclear or strong-interaction scattering amplitude, the results give a much simpler approach to fitting the measured pp and p p cross sections and extracting information on the real part of the forward scattering amplitudes than methods now in use.
