  Measurements of momentum space correlations in heavy ion reactions are a
unique tools to investigate the properties of the created medium. However,
these analyses require the careful handling of the final state interactions
such as the Coulomb repulsion of the involved particles. In small systems such
as $e^+ + e^-$ or $p+p$ the well-known Gamow factor gives an acceptable
description but in the case of extended sources like that are created in heavy
ion collisions, a more sophisticated approach has to be developed. In this
paper we expand our previous work on the investigation of the Coulomb final
state interaction in the presence of a L\'evy source. Such sources were shown
to be a statistically acceptable assumption to describe the quantumstatistical
correlation functions in high energy heavy ion reactions.
