The knowledge of matter and charge radii of lithium isotopes as well as of matter and charge distributions, is an important input in the analysis of the proton [1] and electron [2] scattering experiments, and in the evaluation of the data of the newly proposed isotope shift measurments [3]. The lithium isotopes with mass A ranging from 5 to 11 have been described in the DCM. We discuss the following mix-mode states: {p}+{2p−1h} for 5Li, {h}+{2h−1p} for 7Li, {2p}+{3p−1h} for 6Li, {4p}+{5p−1h} for 8Li, {2p−1h}+{3p−2h} for 9Li, and {3p}+{4p−1h} for 11Li [4]. The calculated radii are in good agreement with the experimental results [5]. Within the calculated matter distribution for 6Li, the proton scattering cross sections of p-6Li at an energy of 0.7 GeV/u can be predicted. The calculated distributions of the lithium isotopes are strongly influenced by the isospin behaviour of the core collective modes.
