The hyperspherical harmonic basis is used to describe the bound states of the three- and four-nucleon systems. Modern nucleon-nucleon potentials plus three-nucleon interactions are considered in configuration space as well as in momentum space. The corresponding binding energies have been calculated with accuracy at the level of 1% or better. The convergence with respect to the number of states included in the expansion is much faster for the momentum space than for the momentum space potentials, due to a less repulsive core at short distances.

Abstract
The hyperspherical harmonic basis is used to describe the bound states of the three- and four-nucleon systems. Modern nucleon-nucleon potentials plus three-nucleon interactions are considered in configuration space as well as in momentum space. The corresponding binding energies have been calculated with accuracy at the level of 1% or better. The convergence with respect to the number of states included in the expansion is much faster for the momentum space than for the momentum space potentials, due to a less repulsive core at short distances.File in questo prodotto:
