摘要：

A modified version of the Gell-Mann-Levy γ-model, including ω-nucleoncoupling, is used to calculate the axial dipole transition matrix element for the 1+,T=1→+,T=0 transition in A=12 nuclei. This model is consistent with phenomenological Dirac dynamics of one-nucleon states, obeys PCAC, and possesses an explicit expression for the axial current in terms of nucleon and meson fields, which permits direct calculation of the exchange-current contribution. © 1979.
