Relativistic complex separable potential of the neutron–proton system

Separable kernels of the NN interaction within Bethe-Salpeter approach

“…where parametersn i , m i , k i , l i (integer), p ci , β 1i , β 2i , α 1i , α 2i (real) are depend on channel [a] under consideration. Such g form factors are used to describe neutron-proton scattering observables (phase shifts, inelasticities, low-energy parameters and deuteron characteristics) for total angular momentum J = 0, 3 in a wide energy range (see [8]- [10]).…”
