The study of the cross sections of the knocking out nucleons provides important infor-mation about the asymptotic behaviour of the scattering amplitude. During the interac-tion of the incident particle with nucleus, its function is distorted. In this case, we are talking about those components of the wave function for which the probability of inter-action with the target is small, i.e. during the collision, only a small part of the target is excited (an elastic collision with only one of its constituent particles). To do this, it is necessary to use the "point" component of the wave function of the incident particle.
