Symmetry Theorems for IsospinInvariant Reactions
Abstract
Symmetry theorems, analogous to those well known for angular distributions and correlations, are given for isospininvariant reactions starting from an initial state of limited complexity. Detailed calculations are carried out when the initialstate isospin does not exceed 32. A statistical generalization is given for averages over experiments starting from different charge states. Some properties of the irreducible tensor operators which arise from recoupling the angular momentum operator to itself are discussed.
