    "abstract": "An improved hyperspherical harmonic method for the quantum three-body problem\nis presented to separate three rotational degrees of freedom completely from\nthe internal ones. In this method, the Schr\\\"{o}dinger equation of three-body\nproblem is reduced to a system of linear algebraic equations in terms of the\northogonal bases of functions. As an important example in quantum mechanics,\nthe energies and the eigenfunctions of some states of the helium atom and the\nhelium-like ions are calculated.",
