- Аннотация: The presence of two topologically different configurations, a dineutron and a cigar-like one, in the spatial wave function for the neutron-rich nucleus He-6 is predicted. In elastic alpha He-6 scattering, the dineutron configuration leads to the appearance of backward maxima in the cross section for elastic alpha He-6 scattering. The cigar-like configuration is responsible for the scattering mechanism involving independent sequential neutron transfer and the formation of the He-5-He-5 virtual system. In order to estimate the contribution of this mechanism, the matrix element for the two-step sequential particle transfer is calculated by a method that takes into account delay in the interaction and which is realized in the QUADRO code. Calculations performed on this basis make it possible to estimate the weight of the cigar-like component in the wave function for the He-6 nucleus.
