Results: The collective shift due to RPA correlations for the response in the neutral channel is explained by the occupation probability of neutrons in the j> = `+1/2 orbital. Many particle–hole or two-quasiparticle excitations have a coherent contribution to form a giant resonance in neutron-rich nuclei for the charge-exchange channel. The IV spin susceptibility displays the isotopic evolution of the collectivity and the underlying shell structure.
