Matrix elements for a generalized spiked harmonic oscillator
Richard L. Hall, Nasser Saad, Attila B. von Keviczky
Closed-form expressions for the singular-potential integrals <m| x^-alpha |n> are obtained with respect to the Gol'dman and Krivchenkov eigenfunctions for the singular potential V(…

Eigenvalue bounds for a class of singular potentials in N dimensions
Richard L. Hall, Nasser Saad
The eigenvalue bounds obtained earlier [J. Phys. A: Math. Gen. 31 (1998) 963] for smooth transformations of the form V(x) = g(x^2) + f(1/x^2) are extended to N-dimensions. In parti…
