N2 - Contributions to the spin-dependent parameter G'0, the coefficient of σ1·σ2τ1·τ2 δ(r1-r2) in the Fermi-liquid interaction, and to the tensor invariants, are related back to elementary-particle exchange. Once finite-range pion-nucleon interactions are used, almost all of G'0 comes from theρ-exchange nucleon-nucleon potential. Using modern parameterizations of the strength in the ρ-channel, we find G'0 to be in the region of 1.5 to 2.4 which agrees well with an empirical determination.
