This book introduces systematically the operator method for the solution of the Schrodinger equation. This method permits to describe the states of quantum systems in the entire range of parameters of Hamiltonian with a predefined accuracy. The operator method is unique compared with other non-perturbative methods due to its ability to deliver in zeroth approximation the uniformly suitable estimate for both ground and excited states of quantum system. The method has been generalized for the application to quantum statistics and quantum field theory. In this book, the numerous applications of...

This book surveys concepts of X-ray materials analysis, including X-ray scattering and interaction between X-rays and matter, plus techniques including high-resolution X-ray diffraction, reflectivity, grazing-incidence small-angle X-ray scattering and more.
