✦ Synopsis

The Compton profile of methane is measured at 4.28 and 10 degrees using high energy electron impact spectroscopy with 25 keV electrons. The 10 degree profile is found to agree with theoretical calculations through q = 5 au. Both esperimental Compton profiles and the best available theoretical profile were fitted by least squares to a potynomiat of form C$$ a,[1 + (c&J* 1 -n-2 from which the electron momentum density and its integer powered moments were calculated. Agreement was found between the lower order moments, but not for the higher moments. The 4.28 degree experiments were used to define a valence shell Compton profile. Excellent agreement was found with the best theoretical results. Electron momentum density moments were also calculated for this data.

The electronic states of the unsaturated organometallic carbene CrCHz are investigated using high-resolution translational energy loss spectroscopy. The observed energy loss feature (1.05 +0.2 eV) is in good agreement with theoretical calculations which predict two higher lying states, 6B, and 6A,
