    "abstract": "The axial exchange current operator that arises from the coupling of the\naxial field to the pion and effective scalar field in nuclei is constructed.\nThe spatial dependence of this exchange current operator may be determined\ndirectly from the nucleon-nucleon interaction. This \"$\\pi\\sigma$\"-axial\nexchange current contributes about 5\\% to the quenching of the nucleon axial\ncurrent coupling constant $g_A^{GT}$ in heavy nuclei.",
