INVESTIGATION OF STRUCTURE IN LANGMUIR-BLODGETT FILMS OF CADMIUM STEARATE AND BEGENATE WITH SMALL NUMBER OF LAYERS BY MEANS OF X-RAY REFLECTROMETRY

The work covers the Langmuir-Blodgett films of the (Cd*992*99+, Ba*992*99+) of the fatty acids (stearic and begenic ones). The law of changing intensity in the even and odd Bragg peaks for one-dimensional lattice with repetition cell of two symmetric fragments at re-distribution of the scattering density between these fragments has been drawn. The kinetics of agitating molecules between Langmuir-Blodgett film bi-layers of barium stearate depending on the sample annealing time at 66 grad. C has been found on base of the neutronic reflectometry data. The structure in the Langmuir-Blodgett film of cadmium stearate has been determined. It has been found that the structure of the near-surface layers is differed from structure of the internal ones. The structural distortions in the Langmuir-Blodgett film of the cadmium begenate at X-ray irradiation (continuous spectrum) have been discovered. The software package for automatic determination of the structure in the Langmuir-Blodgett films according to the X-ray and neutronic scattering has been created. The evaluation of the accuracy in the discovered structural parameters is givenAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
