Isoscalar and isovector magnetic dipole excitation modes are discussed within the frame of a two-state model using a spin- and spin-isospin-dependent effective separable interaction and the RPA. Simple expressions for excitation energies, gyromagneti

The coupling between the isoscalar and isovector monopole resonances in Nnot =Z nuclei is considered in the framework of the random phase approximation. We find that the one-body operator F/sub 1/ = 2(..sigma../sub n/(Z/A)r/sup 2//sub n/-..sigma../su
