Sensitivity of elastic electron scattering off the 3He to the nucleon form factors
Elastic electron-3He scattering is studied in the relativistic impulse
approximation. The amplitudes for the three-nucleon system
- 3He - are obtained by solving the relativistic generalization of the
Faddeev equation. The charge and magnetic form factor are calculated and
compared with the experimental data for the momentum transfer squared up to 100
fm-2. The influence of the various nucleon form factors is investigated
On the Relativistic Separable Functions for the Breakup Reactions
In the paper the so-called modified Yamaguchi function for the Bethe-Salpeter
equation with a separable kernel is discussed. The type of the functions is
defined by the analytic stucture of the hadron current with breakup - the
reactions with interacting nucleon-nucleon pair in the final state (electro-,
photo-, and nucleon-disintegration of the deuteron).Comment: 4 pages, 2 figures, to be published in EPJ Wo
The Separable Kernel of Nucleon-Nucleon Interaction in the Bethe-Salpeter Approach
The dispersion relations for nucleon-nucleon (NN) T-matrix in the framework
of Bethe-Salpeter equation for two spin one-half particle system and with
separable kernel of interaction are considered in the paper. The developed
expressions are applied for construction of the separable kernel of interaction
for S partial-waves in singlet and triplet channels. We calculate the low
energy scattering parameters and the phase shifts and also the deuteron binding
energy with the separable interaction. The approach can be easily extended to
higher partial-waves for NN-scattering and other reactions (anti N N-, pi
N-scattering).Comment: RevTex 4 style, 9 pages, 1 figur
On the relativistic
The bound state of three nucleons is investigated using the Faddeev equations within the Bethe-Salpeter approach. The relativistic and nonrelativistic nucleon-nucleon interaction is chosen in a multirank separable form. The extension for partial-states with L > 0 is done. Three partial-wave states - 1S0,3S1 and 3D1 - are taken into account. The Gauss quadrature method is used to calculate the integrals and find the triton binding energy by iterations
