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 (Formula presented) spin-independent attractive potentials whereas derivative coupling renders (Formula presented) spin-independent repulsive potentials. © 1998 The American Physical Society.
