Matter and charge distributions of He-6 and Li-5,Li-6,Li-7,Li-9 within thedynamic-correlation model - art. no. 067305

The matter and the charge distributions of the He-6 and Li-5,Li-6,Li-7,Li-9 isotopes are investigated within the dynamic-correlation model (DCM) which describes the ground states of light nuclei in terms of microscopic correl ated clusters: the valence particles and the intrinsic vacuum states. The a mplitudes of these mixed-mode wave functions are calculated in the framewor k of nonperturbative solutions of the equation of motion method (EQMM). The matter and charge mean square radii are in good agreement with experimenta l results. The calculated matter distribution of the He-6 nucleus is charac terized by a halo structure less pronounced than that calculated by the thr ee cluster models. The charge distribution of Li-6 reproduces well the elec tron scattering data. Good agreement with experimental data has been also a chieved for the proton scattering cross sections of p-He-6 at an energy of 0.7 GeV/nucleon.
