Magnetization Density of5fElectrons in Ferromagnetic PuSb

Abstract
The magnetization density of 5f electrons in PuSb has been measured by use of a single crystal and polarized neutrons. The spatial extent of the spin and orbital densities is such that the form factor has a maximum at sinθλ0.2 Å1. The ground-state wave function is deduced. Evidence for anisotropic interactions is presented.
