%X A Laue-case X-ray interferometer has been constructed to enable the measurement of X-ray refractive indices for X-ray wavelengths ranging from Ag Krx.1 to Fe Krx.1. Refractive indices have been measured for some alkali and alkaline-earth halides. From these the real part of the X-ray forward scattering amplitude I!J.f~ has been calculated for each atomic species. Comments are made on the validity of some of the assumptions made in quantum mechanical estimations of I!J.f~.
