      Abstract

      The series of calculations of differential cross sections and analyzing powers (Ay) of the elastic proton scattering on isotopes 6He and 8He was presented in the framework of the theory of Glauber multiple diffraction scattering. The three-body {\alpha}-n-n and harmonic oscillator wave functions were used for 6He, for 8He - the function of density distribution in LSSM. For p6He scattering the expansion of the Glauber operator into a series of multiple scattering is written in the form consistent with the picture of weakly bound clusters in halo-nuclei, for p8He scattering the members of single- and double collisions are included in the operator. We have done the comparison of our results with available experimental data (including new data of Ay for p6He scattering at the E = 71 MeV/nucleon) and with the calculations results in the other approaches (high-energy, optical model, RMF). Also, the comparison of the characteristics of two isotopes 6He and 8He was made, which showed that they correlate quite well with each other.

        Matter and charge radius of 6He in the hyperspherical-harmonics approach

        We present ab-initio calculations of the binding energy and radii of the two-neutron halo nucleus 6He using two-body low-momentum interactions based on chiral effective field theory potentials. Calculations are performed via a hyperspherical harmonics expansion where the convergence is sped up introducing an effective interaction for non-local potentials. The latter is essential to reach a satisfactory convergence of the extended matter radius and of the point-proton radius. The dependence of the results on the resolution scale is studied. A correlation is found between the radii and the two-neutron separation energy. The importance of three-nucleon forces is pointed out comparing our results and previous calculations to experiment.
