    "abstract": "A modification of the spiked harmonic oscillator is studied in the case for\nwhich the perturbation potential contains both an inverse power and a linear\nterm. It is then possible to evaluate trial functions by solving an integral\nequation due to the occurrence of the linear term. The general form of such\nintegral equation is obtained by using a Green-function method, and adding a\nmodified Bessel function of second kind which solves an homogeneous problem\nwith Dirichlet boundary condition at the origin.",
