Title: Excitation of molecules by cold electrons Author: Miroslav Šulc Department / Institute: Institute of Theoretical Physics, Charles University in Prague Supervisor of the doctoral thesis: prof. RNDr. Jiří Horáček, DrSc., Institute of Theoretical Physics, Charles University Abstract: Several methods for low energy collisional processes are investigated. In the first part, attention is especially devoted to examination of applicability of the R-matrix method combined with the Schwinger-Lanczos (SL) variational principle for potential scattering with long-range forces. Next sections deal with the development of the interaction correlation-polarization (CP) potential in the framework of the Dis- crete Momentum Representation (DMR) method on the grounds of the Local Density Approximation in the Density Functional Theory (DFT) context. Obtained results are then utilized in body-frame (BF), static exchange + polarization (SEP), calcula- tions within an analysis of experimental data for e−-N2 scattering comprising a part of a larger project addressing theoretical examination of rotational excitations of small molecules in the gas phase induced by electron impact. For N2, a new phenomenon consisting in suppression of backward cross-section below 95 meV is observed and con- sequently attributed to...
