Effects of tensor correlations on low-lying collective states in finite nuclei

Abstract

We present a systematic analysis of the effects induced by tensor correlations on low-lying collective states of magic nuclei, by using the fully self-consistent random phase approximation (RPA) model with Skyrme interactions. The role of the tensor correlations is analyzed in detail in the case of quadrupole (2${}^{+}$) and octupole (3${}^{\ensuremath{-}}$) low-lying collective states in $^{208}\mathrm{Pb}$. The example of $^{40}\mathrm{Ca}$ is also discussed, as well as the case of magnetic dipole states (1${}^{+}$).
