Electron Compton scattering from methane and methane-d4

Cooper, G.; Hitchcock, Adam Percival; Chatzidimitriou-Dreismann, C; Vos, Maarten


Quasi-elastic electron scattering at high-momentum transfer was measured for CH4 and CD4 in the gas phase. At high-momentum transfer, two scattering peaks are observed in each molecule. We interpret the splitting as due to independent Compton scattering from each nucleus, such that, at an impact energy of 2 keV and 100° scattering angle, the peaks for the C and H in CH4 are split by 2.1 eV while those associated with the C and D in CD4 are split by 1.1 eV. These splittings are in agreement with...[Show more]
