摘要：

Using dispersion theoretic techniques, we consider coherent long range forces arising from double pseudoscalar exchange among fermions. We find that Yukawa type coupling leads to 1/r(3) spin-independent attractive potentials whereas derivative coupling renders 1/r(5) spin-independent repulsive potentials. [S0556-2821(98)03721-7]
