The monopole effect of the tensor force is presented, exhibiting how spherical single-particle energiesare shifted as protons or neutrons occupy certain orbits. An analytic relation for such shifts is shown, andtheir general features are explained intuitively. Single-particle levels are shown to change in a systematicand robust way, by using themeson exchange tensor potential, consistently with the chiralperturbation idea. Several examples are compared with experiments.status: publishe
