dc.descriptionThe He-4 d elastic scattering at the momentum of 19.8 GeV/c is analyzed in the framework of the Glauber theory. The scattering amplitude was evaluated using different sets of values of the nucleon-nucleon amplitude parameters and the He-4 density function as a superposition of the Gaussian functions. It is shown that it is impossible to describe simultaneously the pHe-4 and dHe-4 elastic scattering cross sections using the same set of the NN-amplitude parameters. Inclusion of the twelve quark bag admixture to the ground state of the He-4 nucleus in the calculations allows one to reproduce the experimental data quite well. It is shown that the admixture manifests itself in the dHe-4 elastic scattering in all region of the momentum transfer. At small t the effect can be at the level of ~ 10 %. At large t it can be ~ 30 %.
