Abstract
We present a thorough analysis of the effects of tensor interaction on the multipole response of magic nuclei, using the fully self-consistent random phase approximation model with Skyrme interactions. We disentangle the modifications to the static mean field induced by the tensor terms, and the specific features of the residual particle-hole (p-h) tensor interaction, for quadrupole (), octupole (), and also magnetic dipole () responses. It is pointed out that the tensor force has a larger effect on the magnetic dipole states than on the natural parity states and , especially at the mean-field level. Perspectives for a better assessment of the tensor force parameters are discussed.
