Core Electrons

Experimental angular correlation curves for identically oriented single crystals of copper, silver, and gold have been obtained using "a point geometry" apparatus. The differences between these angular correlation data are compared to the differences predicted using a simple model of the Fermi surface combined with calculations of the theoretical core distributions.

Electron Theory

Electron momenta in Pb and PbIn alloys were measured by the positron annihilation technique. The distributions of momentum observed in single crystals of the specimens showed appreciable anisotropy. A model of the known Fermi surface of Pb near the (111) zone face was adjusted to fit the data. A similar model for the alloys was used to determine kF as a function of In concentration in the range 0 < In < 48 at.%. The results are remarkably like free electron theory.
