Abstract

The role of short-range and tensor correlations in spin isospin longitudinal (q·σ) and transverse (q×σ) responses of a finite nucleus is studied in detail by using a sum rule approach. The tensor effects concur in favouring a spin-isospin ordered phase in the longitudinal response which results enhanced. They give the opposite contribution in the transverse channel. The influence of the dynamical correlations on the mean energies of the two responses is also discussed.
