Electrodisintegration of 3 He below and above deuteron breakup threshold

Recent advances in the study of electrodisintegration of 3 He are presented and discussed. The pair-correlated hyperspherical harmonics method is used to calculate the initial and final state wave functions , with a realistic Hamiltonian consisting of the Argonne v18 two-nucleon and Urbana IX three-nucleon interactions. The model for the nuclear current and charge operators retains one-and many-body contributions. Particular attention is made in the construction of the two-body current operators arising from the momentum-dependent part of the two-nucleon interaction. Three-body current operators are also included so that the full current operator is strictly conserved. The present model for the nuclear current operator is tested comparing theoretical predictions and experimental data of pd radiative capture cross section and spin observables.
