Abstract

Inelastic scattering of Li11 on proton targets at energy of 68MeVnucleon has been studied in the microscopic four-body distorted-wave model. The ground state and three-body continuum excitations of Li11 were calculated in the Li9+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 Li11 and from its soft dipole excitation. Various aspects of the Li11 excitations and their nature are discussed in terms of correlation plots.
