The method of proton elastic scattering at intermediate energies, which was already proven for neutron-rich helium isotopes to be well suited for obtaining accurate and detailed information on nuclear matter distributions of halo nuclei[1], was recently applied for the investigation of neutron-rich Li-isotopes using ^6,8,9,11Li beams at energies around 700 MeV/u. The experimental setup consisted of the ionization chamber IKAR which served simultaneously as high-pressure hydrogen target and as recoil proton detector, and a forward spectrometer for tracing and identifying the projectile nuclei after the scattering process. The status of the data analysis, and preliminary results on the nuclear matter distributions deduced with the help of the Glauber multiple scattering theory will be presented.
