A COMPLEMENT TO GOLDSTEIN-MORAVCSIK THEOREM
A. R. Usha Devi, A. Sudha Rao, G. Ramachandran · Modern Physics Letters A · 1995
As a complement to Goldstein-Moravcsik theorem, we show that in parity conserving reactions with spin structure 0+1/2→1+1/2 the differential cross-section [Formula: see text] and the vector polarization [Formula: see text] of spin-one particle are sufficient to determine the amplitudes unambiguously and there is no need to measure the tensor polarization [Formula: see text].
