Symmetry Theorems for Isospin-Invariant Reactions

Phys. Rev. 121, 636 – Published 15 January 1961
Murray Peshkin


Symmetry theorems, analogous to those well known for angular distributions and correlations, are given for isospin-invariant reactions starting from an initial state of limited complexity. Detailed calculations are carried out when the initial-state 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.
