Abstract
A convenient parametrization of experiments in which a polarized spin-1 particle bombards a target and a polarized spin-1 particle emerges is given. The parameters defined are a generalization of the "Wolfenstein parameters" long used in the description of spin- polarization-transfer experiments. A specific matrix for a spin-0 target is used to find the relations between the various observables in several coordinate systems. The formalism is valid for the general 1 + 0 → 1′ + 0′ problem, where 1 and 1′ may indicate different spin-1 particles and 0 and 0′ may indicate different spin-0 particles, but where the product of initial channel and final channel parities is unchanged. The constraints imposed by time-reversal invariance when the reaction is specialized to elastic scattering are discussed. The prospects for a complete determination of the matrix and for possible time-reversal tests are briefly touched upon.
