Quasi-elastic electron scattering at high momentum transfer was measured the gas phase. At high momentum transfer, two scattering peaks are observed We interpret the splitting as due to independent Compton scattering from that, at an impact energy of 2 keV and 100o scattering angle, the peaks for are split by 2.1 eV while those associated with the C and D in CD4 are split splittings are in agreement with those predicted from Rutherford scattering single atoms. The widths of the C, H and D peaks are very different, and of their momentum. The lineshapes of the H(D) peaks are in agreement space vibrational wavefunction. Detailed peak area analysis reveals anomalously for the hydrogen and deuterium peaks relative to the carbon peak ? the theoretical C:H ratio is 9.0, compared with 9.8(2) (C:H) and 9.7(2) (C:D) measured possible explanations for this discrepancy, one due to deviations of the actual the Rutherford values, the other due to short lived quantum entanglement, Rutherford scattering interpretation is compared to that for vibrational Compton- predicted by Bonham and de Souza (J. Chem. Phys, 79 (1983) 134).
