Evaluation of cross-section data for various collision processes is now being made by many groups. But the results (i.e., recommended data) are often different from each other depending on who eval...

Electron-impact excitation of vibrational motion of molecules is reviewed, particularly for polyatomic molecules. A polyatomic molecule has multiple modes of vibration. The excitation cross sections for different modes show different behaviour as a f
