ABSTRACT:
An x-ray diffraction crystal for the analysis of x-rays having a wave-length of 50 Angstroms or greater comprising at least two insoluble monolayers of fatty acids in the form of metal soaps, separated by monolayer pairs of differing metal cation - metal soap or non-cation soaps.
Such crystals are formed by alternately raising and lowering a solid substrate through the monolayer-covered liquid surfaces of a bivalent heavy element cation and a bivalent light element cation or cation deleted monolayer.
