  The electric dipole response of the halo nucleus $^{11}$Li is calculated in a
hyperspherical three-body formulation, and is studied as a function of the
interaction employed for $n-^9$Li to reflect the Pauli principle. Strength
concentrations at lower energies are found but no narrow resonances. Only one
possible scenario of $^{11}$Li structure is in close correspondence with MSU
and RIKEN experimental data.
