Solid body and liquid superficial structure study by ellipsometry considering mathematical inverse problem incorrectness. Part 5. About real possibilities of successive approximations in the solution of the inverse problem

The work is devoted to successive approximation method intended for the solution of mathematically an incorrect inverse problem for one-layer system with the transparent ultra-thin film. The earlier developed method is not only simplified, but also is considerably improved. First of all it concerns a sign on which optimum value of an absorption constant of a substrate is determined. The new variant of the method can be successfully used to study the superficial structure of different objects, including fluids.
