Abstract

Two- and three-particles photodisintegration of the triton is investigated in a three-dimensional (3D) Faddeev approach. For this purpose the Jacobi momentum vectors for three-particles system and spin-isospin quantum numbers of the individual nucleons are considered. Based on this picture the three-nucleon Faddeev integral equations with the two-nucleon interaction are formulated without employing the partial-wave decomposition. The single-nucleon current as well as π- and ρ-like exchange currents are used in an appropriate form to be employed in the 3D approach. The exchange currents are derived from AV18 NN force. The two-body t-matrix, deuteron and triton wave functions are calculated in the 3D approach by using the AV18 potential. Benchmarks are presented to compare the total cross-section for the two- and three-particles photodisintegration in the range of E γ < 30 MeV. The 3D Faddeev approach shows promising results.
