    "abstract": "The angular momentum (partial wave) reduction of the Lippmann--Schwinger\nequation describing the interaction of two spin 1/2 particles is extended to\nthe case in which the spin singlet and triplet states are coupled. A straight\nforward method for obtaining the angular momentum decomposition of the general\npotential is indicated. The derived formalism is needed to describe the\ninteraction between two nonidentical spin--1/2 particles or between two\nnucleons when isospin symmetry is violated. The resulting modification of the\nStapp phase--shift analysis is given.",
