photodisintegration of 3H in a three dimensional Faddeev approach — shahriar bayegan, •mehdi ahmadian shalchi, and mohammad reza hadizadeh — Department of Physics, University of Tehran, P.O.Box 14395-547, Tehran, Iran
An interaction of a photon with 3H nuclei is investigated based on a three dimensional Faddeev approach. In this approach The three-nucleon Faddeev equations with two-nucleon interactions are formulated with consideration of the magnitudes of the vector Jacobi momenta and the angle between them with the inclusion of the spin-isospin quantum numbers, without employing a partial wave decomposition. In this calculation the two body t matrices and triton wave function with nd scattering are calculated in the three dimensional approach using AV18 potential. The standard single nucleon current and π-and ρ-like two-body currents have been used which fulfill the current continuity equation together with the corresponding parts of the AV18 potential. Finally the calculated observables are compared with the results of partial wave one and the experimental data.
