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 oscillat or potential [Aguilera-Navarro et al., J. Math. Phys. 31, 99 (1990)]. (C) 1 998 American Institute of Physics. [S0022-2488(98)00812-3].
