Abstract

The properties of the low-lying 2⁺ states in the even-even nuclei around 132Sn are studied within the quasiparticle random phase approximation. Starting from a Skyrme interaction in the particle-hole channel and a density-dependent zero-range interaction in the particle-particle channel, we use the finite rank separable approach in our investigation. It is found that the fourth 2⁺ state in 132Te could be a good candidate for a mixed-symmetry state.
