“…An anisotropy much lower than that known for cubic systems (see, for example, [18,[30][31][32]36]) can probably be expected, based on the purely geometrical properties of the lattice. Similarly small anisotropy has been observed recently in rhombohedral bismuth [37]. However, it is also well known that observed amplitudes of the oscillations in cubic systems (in which anisotropy itself reaches 0.05-0.1 electron per au) are as a rule two times lower than theory indicates.…”

We have measured the directional Compton profiles of a single crystal of hexagonal zinc along the [00·1], [10·0], [11·0] and [11·1] directions using high-energy (662 keV) gamma radiation from a 137Cs isotope source. The experimental data have been compared with the corresponding theoretical Korringa-Kohn-Rostoker semi-relativistic calculations. The theory slightly overestimates the electron momentum densities at low momenta regions for all measured profiles. The directional difference profiles, both experimental and theoretical, show very small anisotropy of the electron momentum density in hexagonal zinc, at most half of that presented in the literature for cubic systems.

In this paper, we present the first experimental Compton profile of ytterbium. Measurement has been made, at an intermediate resolution (0.40 a.u.), using gamma-ray Compton spectrometry employing a 20 Ci 137 Cs source. In the absence of band-structure calculations, the experimental profile is compared with a free-electron model-based profile and renormalised free-atom (RFA) model. It is seen that the RFA results are comparatively in better agreement with the experiment. Using our Compton profile measurement, we have also derived the cohesive energy of ytterbium.
