Abstract: Attenuation lengths in cadmium arachidate [(C19H39COO)2Cd] multilayer Langmuir–Blodgett films deposited on thick lead arachidate [(C19H39COO)2Pb] films have been determined in this communication. A discrete layer model appropriate to the ordered structure of these built-up films is proposed and applied for the first time to the measurements of the x-ray photoemission intensity variation with electron takeoff angle and attenuation lengths for 950–1350 eV electrons are evaluated. These lengths agree with earlier attenuation length measurements in Langmuir–Blodgett films and are higher than in most inorganic materials. [ABSTRACT FROM AUTHOR]
