Abstract
The Correlated Hyperspherical Harmonic Method is used to describe bound and scattering states in few-body systems. Special attention is given to the three-nucleon problem in which the presence of correlation factors substantially accelerate the convergence of the expansion. For scattering states the complex form of the Kohn variational principle is used to determine the S- or T-matrix. Using this formalism the method can be extended to energies above the three-body breakup threshold. Using realistic NN interactions comparisons to experimental data are given.
