Cálculo de las integrales radiales en dispersión de electrones
The radial integrals which arise from the distorted wave treatment of photon emission process in electron and positron scattering, involve products of the electron`s (or positron`s) ingoing and outgoing wave functions and the radial part of the electromagnetic Green`s function. They can be performed...

| Summary: |
The radial integrals which arise from the distorted wave treatment of photon emission process in electron and positron scattering, involve products of the electron`s (or positron`s) ingoing and outgoing wave functions and the radial part of the electromagnetic Green`s function. They can be performed analytically for point Dirac-Coulorab wave functions, but are difficult to evaluate because they involve slowly converging doubly infinite series. We present a discussion and review of the formulation and methods employed to calculate these basic integral at a given value of the energy trafer. |
