Interference of different potential amplitudes in mutual scattering of the lightest clusters

The orbital Young scheme (f) is rather good quantum number in light nuclei. In this case the S-matrix for the scattering of clusters A1+A2 can be expressed in terms of phase shifts δe(f). The d+d scattering with vanishing spin S=0 is considered. The resonating-group method (RGM) equations are projected onto channels with the definite (f) value. The RGM integral kernels are transformed into equivalent local potentials V(f)e. It is shown in the d+d scattering the inteference of amplitudes with (f)=(4), (22) takes place and the relation of depths of these potentials is V(4)/V(22) ∼ 4. Such an approach can be extended on the NN-scattering problem in a quark model
