Abstract: (APS)
A three body model for 11Li proposed earlier [S. Dasgupta et al., Phys. Rev. C 50, R510 (1994)] employing separable potentials for n−n and n−9Li interactions has been extended to study the recently observed excited states in 11Li above the three body breakup threshold. The n−9Li potential used here includes both s- and p-state interactions so as to incorporate the virtual s-state and p-wave resonance observed experimentally. The resulting coupled integral equations for the spectator functions have been computed using the method of rotating the integral contour of the kernels in the complex plane. The model predicts the ground state energy as well as the three excited states in reasonable agreement with the data recently obtained. Dynamical content of the two body input potentials in the three body wave function has also been analyzed through the three-dimensional plots.- 21.10.Dr
