Within the framework of the relativistic plane wave impulse approximation, we study the observable consequences of employing a complete Lorentz invariant representation of the nucleon-nucleon (AW) scattering matrix in terms of 44 independent amplitudes, as opposed to the previously employed, but ambiguous, five-term Lorentz invariant parametrization of the NN scattering matrix, for the prediction of complete sets of exclusive (p, 2p ) polarization transfer observables. Two kinematic conditions are considered, namely, proton knockout from the 3s1/2 state of 208Pb at an incident energy of 202 MeV for coplanar scattering angles (28.0°,-54.6°), as well as an incident energy of 392 MeV for the angle pair (32.5°,-80.0°). The results indicate that certain spin observables are ideal for discriminating between the two representations.
