- Abstract
Starting from an effective Skyrme interaction, we study the effects of phonon-phonon coupling on the low-energy spectrum of the 1- states in 132Sn. The calculations are performed within a finite rank separable approximation for the particle-hole interaction. The inclusion of two-phonon configurations brings a sizeable contribution to the low-lying strength. Comparison with available experimental data shows a reasonable agreement for the low-energy E1 strength distribution.
