Valence Orbitals of Ethane by Electron Momentum Spectroscopy

The valence electron binding energy spectra and orbital electron momentum distributions of ethane(C₂H₆) have been measured by high resolution (ΔE=0.9eV, Δp = 0.1 a.u.) symmetric non-coplanar electron momentum spectroscopy, at an impact energy of 1200eV+binding energy. The high energy resolution is adequate for us to be observe clearly the separated valence orbitals of C₂H₆.
