In a consideration of the tunneling and the propagation of the particle in relation to the barrier with accounting of processes of multiple internal reflections the expression of S-matrix for elastic scattering is represented in a form of summ of two components corresponding to the propagation and the reflection of the particle in relation to the barrier.The adequacy of our notions of even-even nuclei as rotators with static deformation is shown. In the framework of time-analysis the energy dependence of the radius of the real part of the nucleon-nucleus potential of the dispersion optical model is explained with regard for binded and virtual states of compound nucleus. The helicities of produced vector meson and virtua l photon in deep inelastic scattering are shown to be equal in the framework of perturbative QCD.
