On the Coulomb shifts of nuclear resonances at low energies

摘要

The relationship between the shift of a resonance and the interacion potential is obtained in the frame of coupling constant evolution method. Analysis of the Coulomb shifts of resonance energies and widths has been carried out for nuclear cluster systems at low energies. The nature of these shifts is investigated in the examples of p, and p,6Li scatterings. For simplicity a model using separable potentials describing two-body nuclear scattering resonances. The results of the calculation are in accordance with experimental data. In the case of the two -particles system the relationship shows that the Coulomb shift of , -resonance remains small.
