Proton-helium elastic differential cross sections at high energies has been calculated ?within the framework of the Glauber approximation using various parametrizations of He4 form-?factor. Inclusion of admixture of the hypothetical 12-quark bag state (to account collectively for ?multiquark states) in the ground state wave function of the He4 nucleus into the differential cross ?section calculations has been performed. It is shown that the admixture allows one to describe ?quite well the elastic p+He4 scattering. More than 20 sets of experimental data has been fitted, ?and it was founded that the weight of the 12q bag in He4 nucleus is about 10.5%, the proton - ??12q bag total cross section is about 34mb, and the slope parameter of the p+12q bag elastic ?scattering is about 23 (GeV/c)-2.? The admixtures of 12q bag state to the ground state of the He4 nucleus taken into account ?in different interactions of He4 with different nuclei, n+A, and nucleus + nucleus a good ?agreement with...
