Abstract
We show the equivalence of a previously derived exact expression for t he response of a non-relativistic system with harmonic forces and an i nfinite sum of weighted delta-functions corresponding to the spectrum. We forward arguments, indicating that the Gersch-Rodriguez-Smith 1/q- expansion of the response does not converge and prove that this expans ion is an asymptotic series.
