In the investigation of problems in surface chemistry it is possible to impose

difference in scattering powers for neutrons between protons and deuterons.

In the investigation of problems in surface chemistry it is possible to impose

**constraints**upon the model fitting. The first of these results forms the largedifference in scattering powers for neutrons between protons and deuterons.
