When we perform similar non-relativistic expansions for scalar and vector mesons we obtain for the σ meson Vσ=g2σNN1k2+m2σ(−1+q22M2N−k28M2N−LS2M2N). We note an attractive central force and spin-orbit force. This term has an intermediate range. We have defined 1/2(p1+p′1)=q. For the full potential add the exchange part and the isospin dependence as well.
