✦ Synopsis

Invariance arguments are used to derive the most general velocity dependent charge independent two-nucleon interaction in the nonrelativistic approximation. If one stays on the energy shell, the only essentially new term in the twonucleon interaction is the quadratic spin-orbit potential. Off the energy shell, the quadratic spin-momentum potential must be treated as independent. In meson theory, the quadratic terms arise as (&W)% b is the pion mass, M the nucleon mass) corrections to the second-order static potential in contrast to the linear spin-orbit potential which originates as a b/M) correction to the fourth-order static potential.
