There is experimental evidence of an increase in the temporal component of the weak axial vector current in nuclei. Most of this increase is accounted for by meson exchange currents. We consider further corrections from pions and the sigma mean-field. These corrections, however, are found to reduce the coupling, which is already insufficiently large.
