Abstract
Eigenvalues of the ground state of the radial Schrodinger equation for a spiked harmonic-oscillator potential have been evaluated employing two methods: numerically, via the Lanczos/grid technique, and by means of standard Pade approximants constructed from an expansion of large coupling parameter series for the energy. Numerical results are compared for several values of the parameters characterizing the spiked singular potential.Keywords
