Two component covariant formalism of Stapp has been used to have the completely Lorentz invariant model. In addition to the Impulse Approximation the nucleon-nucleon double-scattering and delta-excitation mechanism have been added coherently. Good agreement with the precise data obtained at Saclay is achieved.45 pages, 11 figuresNuclear TheoryDeutron Break-Up: Theoretical Description of Polarization Observables in Stapp formalismtext
