    "abstract": "Nuclear PCAC relation is studied in the framework of the effective theory of\nnuclear interaction, in which the interaction of real pion\nproduction-absorption is expressed by many-body operators, and does not include\nthe one-nucleon operator as was assumed in the conventional works, while the\neffective axial-vector current includes the one-nucleon current in contrast to\nthe former interaction. This problem is investigated under the simple linear\n$\\sigma$-model. Results are as folows: 1) The theory describes consistently the\nPCAC relation and the pion production-absorption process. 2) The conventional\ninterpretation of the effective pion source function as the interaction\nHamiltonian of pion production-absorption does not hold. 3) The effective pion\nsource function still includes the one-nucleon operator for the pion\nproduction-absorption at threshold effectively, which may justify the\nconventional theory.",
