Abstract
A recently developed variational scheme is applied to the calculation of the ground-state and excited-state energies of an electron bound in a screened Coulomb potential. A basis of independent functions is gen erated by expanding an initial trial wavefunction around a variational parameter. The calculated eigenenergies are compared with other varia tional methods and the exact results. (C) 1998 Elsevier Science B.V.
