Relativistic rank-one separable kernel for helium-3 charge form factor
arXiv:2010.15540 · doi:10.1016/j.nuclphysa.2020.122065
Abstract
Elastic electron-helium-3 scattering is studied in the relativistic impulse approximation. The amplitudes for the three-nucleon system are obtained by solving the relativistic generalization of the Faddeev equations with a separable rank-one kernel of the nucleon-nucleon interaction. The contribution of partial-wave states with nonzero orbital moment of a nucleon pair is investigated. The static approximation and additional relativistic corrections for the 3He charge form factor are calculated for the momentum transfer squared up to 100 fm^-2. The contribution of the 3D1 partial-wave state and relativistic corrections are found to be sizable at high energies.
