Treatment of the continuum spectrum of a scattering system by a discrete set of pseudostates generated by the diagonalization of the Hamiltonian in square-integrable basis functions results in spurious resonances. An energy-averaging procedure is formulated using the Stieltjes mean values for the spectral density. The connection between this L/sup 2/ basis approach to scattering problems and the stabilization method is discussed, and an improved form of the latter is derived.
