Abstract
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.
