Energy bounds for a class of singular potentials and some related series
Nasser Saad, Richard L. Hall, Attila B. von Keviczky
Perturbation expansions up to third order for the generalized spiked harmonic oscillator Hamiltonians H = -d^2/dx^2+ x^2 + A/x^2 + lambda/x^alpha, A >= 0, 2gamma > alpha, gamma=1+(…

Generalized comparison theorems in quantum mechanics
Richard L. Hall, Qutaibeh D. Katatbeh
This paper is concerned with the discrete spectra of Schroedinger operators H = -Delta + V, where V(r) is an attractive potential in N spatial dimensions. Two principal results are…
