dc.description.abstract | We present angular basis functions for the Schrödinger equation of two-electron systems in hyperspherical coordinates. By using the hyperspherical adiabatic approach, the wave functions of two-electron systems are expanded in analytical functions, which generalizes the Jacobi polynomials. We show that these functions, obtained by selecting the diagonal terms of the angular equation, allow efficient diagonalization of the Hamiltonian for all values of the hyperspherical radius. The method is applied to the determination of the [Formula Presented] energy levels of the [Formula Presented] and we show that the precision can be improved in a systematic and controllable way. © 2000 The American Physical Society. | en |
