    "abstract": "The problem of calculating the four--nucleon bound state properties for the\ncase of realistic two- and three-body nuclear potentials is studied using the\nhyperspherical harmonic (HH) approach. A careful analysis of the convergence of\ndifferent classes of HH functions has been performed. A restricted basis is\nchosen to allow for accurate estimates of the binding energy and other\nproperties of the 4He ground state. Results for various modern two-nucleon and\ntwo- plus three-nucleon interactions are presented. The 4He asymptotic\nnormalization constants for separation in 2+2 and 1+3 clusters are also\ncomputed.",
