Matrix elements for a generalized spiked harmonic oscillator

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 Bx(2) +A/x(2), B >0, A greater than or equal to 0. The formulas obtained are generalizations of those found earlier by use of the odd solutions of the Schrodinger equation with the harmonic oscillator potential [Aguilera-Navarro et al., J. Math. Phys. 31, 99 (1990)]. (C) 1998 American Institute of Physics. [S0022-2488(98)00812-3].
