Highly polarizable metastable 
and
atoms have been diffracted from a
100
period silicon nitride transmission grating and the
van der Waals coefficients C3 for the interaction of the
excited atoms with the silicon nitride surface have been
determined from the diffraction intensities out to the 10th
order. The results agree with calculations based on the
non-retarded Lifshitz formula.
