The basic stochastic theory of narrow nuclear resonance proling is presented. We show that nm depth resolution is achievable inadequate for instrument functions which vary only slowly over the depth range corresponding to the depth resolution, are un-satisfactory for narrow resonance proling in the near surface region. Here, the system response to a delta function concentrationprole varies very rapidly. However, the shape of the excitation curve is very sensitive to certain kinds of small changes in theconcentration prole in the surface region. We discuss some rst eorts to dene a more general concept for depth resolution,to variations in the underlying concentration prole.. 2002 Elsevier Science B.V. All rights reserved.
