Abstract: The periodic structure of arachidic acid salt LBfilms measured by low angle X-ray diffraction will be datnaged by treating LBfilms with vapor of ammonia and hydrogen chloride solution.However, the peaks of the LBfilms, whose diffraction peaks had already disappeared due to the treatment with acid(or base), will be appeared more or less if being treated with base(or acid)again.

Key words: Langmuir-Blodgett films, X-ray diffraction, Treatment of ammonia and hydrogen chloride, Lead arachidate, cadmium aracmdate and barium arachidate
