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.
