摘　　要：We establish the formalism of nuclear spin-isospin excitations, especially the Gamow-Teller (GT) resonance in a fully consistent relativistic random phase approximation. A relativistic form of the Landau-Migdal parameter g'=0.6 is adopted as a residual spin-isospin correlation force. In the non-relativistic limit it reproduces the excitation energy of the giant Gamow-Teller resonance state obtained in the non-relativistic model.
