Abstracts

EN

In the present contribution I focus on various effects affecting the slope of calculated electron-positron momentum densities for electrons from individual core shells. In particular, I discuss the influence of positron distribution, of approximation used for the electron-positron correlation functions, as well as of finite apparatus resolution on the resulting spectra.
