A general procedure for an algebraic formulation of the eigenvalue problem for hamiltonians which have both a discrete and a continuum spectrum is introduced. The onedimensional hiorse potential is used as an example, but more comples types of spectra can also be handled. ## 1 _ Introduction The n

The Lippmann-Schwinger equation for the reactance operator is converted into a system of linear equations. By using spline functions the principal-value singularity of the integral kernel can be treated analytically. Throughout this work recurrence relations suitable for automatic computation are de
