摘要: High-energy electron and X-ray scattering cross-sections of O2, F2, CO CO2 have been calculated within the framework first Born approximation from MR-SDCI wavefunctions recovering up to 92% estimated correlation energy. In contrast fair agreement found for cross-sections, comparison with available experimental data shows large deviations in case scattering. Possible causes observed discrepancies are discussed.
