Electromagnetic Dipole Response as a Test of the $^{\bf 11}$Li g.s. Structure and the n-$^{\bf 9}$Li Interaction

Authors

Description

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.
