N2 - 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 (NN) 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 [Formula Presented] polarization transfer observables. Two kinematic conditions are considered, namely, proton knockout from the [Formula Presented] state of [Formula Presented] at an incident energy of [Formula Presented] for coplanar scattering angles [Formula Presented], as well as an incident energy of [Formula Presented] for the angle pair [Formula Presented]. The results indicate that certain spin observables are ideal for discriminating between the two representations.
