Model independent analysis of polarization effects in elastic proton-electron scattering

The experimental observables for the elastic reaction induced by protons on electrons are calculated in the Born approximation. Model independent expressions are derived for the differential cross section and polarization observables. Numerical estimations are given for spin correlation coefficients, polarization transfer coefficients and depolarization coefficients, in a wide kinematical range. Specific attention is given to the kinematical conditions, i.e., to the specific range of incident energy and transferred momentum.
