Abstract
For a system of spinless particles in a state of definite angular momentum with definite component , the rotational symmetry properties of the two-particle density matrix are obtained in a completely explicit fashion. Also studied is the 2-matrix associated with an equally weighted (unpolarized) ensemble of the various states for a given .
