    "abstract": "The method of effective interaction, traditionally used in the framework of\nan harmonic oscillator basis, is applied to the hyperspherical formalism of\nfew-body nuclei (A=3-6). The separation of the hyperradial part leads to a\nstate dependent effective potential. Undesirable features of the harmonic\noscillator approach associated with the introduction of a spurious confining\npotential are avoided. It is shown that with the present method one obtains an\nenormous improvement of the convergence of the hyperspherical harmonics series\nin calculating ground state properties, excitation energies and transitions to\ncontinuum states.",
