He3andH3bound state for the Reid soft-core potential

The perturbational approach that has been used for the calculation of the triton bound state is applied to ${}_{}{}^3{}_{}{}^{}\mathrm{He}$. The Coulomb potential is fully taken into account within the limitation of the Reid soft-core-3 potential. We obtain 5.775 MeV as the binding energy of ${}_{}{}^3{}_{}{}^{}\mathrm{He}$. The Coulomb energy difference with ${}_{}{}^3{}_{}{}^{}\mathrm{H}$ is 0.625 MeV. The Coulomb effects to the charge form factor and the two-body correlation function are calculated. Qualitative discussions are given for the complex behavior of the Faddeev components expressed in terms of the spectator momentum and the relative distance of the interacting pair.
