    "abstract": "We present a translationally invariant formulation of the no-core shell model\napproach for few-nucleon systems. We discuss a general method of\nantisymmetrization of the harmonic-oscillator basis depending on Jacobi\ncoordinates. The use of a translationally invariant basis allows us to employ\nlarger model spaces than in traditional shell-model calculations. Moreover, in\naddition to two-body effective interactions, three- or higher-body effective\ninteractions as well as real three-body interactions can be utilized. In the\npresent study we apply the formalism to solve three and four nucleon systems\ninteracting by the CD-Bonn nucleon-nucleon potential. Results of ground-state\nas well as excited-state energies, rms radii and magnetic moments are\ndiscussed. In addition, we compare charge form factor results obtained using\nthe CD-Bonn and Argonne V8\u0027 NN potentials.",
