Abstract

Diffraction gratings in which the grating lines have rectangular profile of widths equal to the intervals between them give, when used for X-ray spectroscopy, all diffraction orders, even and odd ones, with essentially the same intensity. The fact that the even orders are not extinguished, not even weaker than the odd ones, proves that the main contribution of the diffracted radiation does not start from the plain surfaces of the lattice lines but from their back sides.
