Abstract
The consequences of the invariance under rotations and reflections of the collision matrix are expressed as a relationship between the expectation values of initial-state and final-state irreducible tensor operators in spin-orbit space. This relationship is used to give a proof of the Eisner-Sachs theorem on the complexity of angular distributions of nuclear reactions and some extensions of this theorem.Keywords
