    "abstract": "We calculate the energies of ground and three low lying excited states of\nconfined helium atom centered in an impenetrable spherical box. We perform the\ncalculation by employing variational method with two-parameter variational\nforms for the correlated two-particle wave function. With just two variational\nparameters we get quite accurate results for both ground and excited state\nenergies.",
