Structure of theLi11continuum from breakup on proton target

Inelastic scattering of {sup 11}Li on proton targets at energy of 68 MeV/nucleon has been studied in the microscopic four-body distorted-wave model. The ground state and three-body continuum excitations of {sup 11}Li were calculated in the {sup 9}Li+n+n cluster model using the method of hyperspherical harmonics. The theory describes the experimental data well and clarifies contributions from the three-body monopole resonance in {sup 11}Li and from its soft dipole excitation. Various aspects of the {sup 11}Li excitations and their nature are discussed in terms of correlation plots.
