Calculation of geometrical structure coefficients for the trinucleon system with central and tensor interactions.

Abstract

We report an efficient method for the calculation of geometrical structure coefficients for coupling between all symmetry components of the wave function for the trinucleon system through central and tensor interactions, which makes the calculation of geometrical structure coefficients simple, economical, and accurate. We also derive sum rules for all kinds of geometrical structure coefficients which can be utilized as an independent check for the calculated geometrical structure coefficients. We compare the present and other existing methods for calculating geometrical structure coefficients for S-S coupling and also report the accuracy of calculated geometrical structure coefficients for coupling between other symmetry components of the wave function.
