A recently developed three-dimensional approach (without partial-wave decomposition) is considered to investigate the solutions of Faddeev-Yakubovsky integral equations in momentum space for three- and four-nucleon bound states, with and without the three-nucleon forces. Three-Dimensional formalism based on the momentum vectors, according to the number of spin-isospin states that one takes into account, leads to only a strictly finite number of the coupled three-dimensional integral equations, with less complicated kernels, to be solved. For binding energies calculations, the spin-dependent nucleon-nucleon (NN) potential models are considered along with the scalar two-meson exchange three-body potential.
