Abstract
The application of the hyperspherical harmonics method to the case of non-local potentials is described. Given the properties of the hyperspherical harmonic functions, there are no difficulties in considering the approach in both coordinate and momentum space. The binding energies and some scattering observables of A = 4 systems are calculated using modern two-body potentials. For the alpha-particle, the results are shown to be in excellent agreement with corresponding ones obtained by other techniques. A study of the n - H-3 scattering lengths is also reported.File in questo prodotto:
