Four-nucleon problem in the integral equation approach

摘要: Abstract Integral equations of motion for the system consisting four pair-wise interacting nucleons are formulated. The nucleon-nucleon interaction is characterized by a charge-independent, spin-and isospin-exchange central potential general (local or non-local) form. derivation performed on basis Faddeev-Yacubovsky method taking Pauli principle strictly into account. obtained describe all possible processes in four-nucleon with two-fragment initial asymptotic state, as well bound states. calculations 4 He binding energy and n- 3 H scattering lengths carried out case separable rank-1 potentials application Bateman approximation subsystem amplitudes. correlations between calculated quantities their sensitivity to parameters NN studied. results compared available experimental data.
