Abstract
The dynamical effect of the neutron-proton mass difference on charge asymmetry in the trinucleon system is investigated using perturbation theory and the Faddeev equations. The mixed symmetry components of the wave function play an unexpectedly critical role and reduce the effect by roughly a factor of 2 from simple estimates. A reduction rather than an enhancement occurs because the neutron-proton force is stronger than the neutron-neutron or proton-proton forces.
