Inverse proton scattering from unstable nuclei with halo

Proton scattering studies from a halo nucleus ¹¹Li are presented which elucidate its unsual structure. The elastic and inelastic ¹¹Li+p scattering data have been analysed in a coupled channel approach with folded potentials. The analysis delineats that elastic scattering is sensitive to the extent of halo structure at lower incident energy at very forward laboratory angles. The inelastic scattering angular distribution is found to be consistent with the idea of a soft dipole resonance characterising a halo nucleus.
