High neutron polarization ratio (>95%) has been achieved at the HFIR HB-3A single crystal neutron diffractometer. This is the first use of this capability on an experiment approved through the General User program. We succeeded in detecting a weak itinerant ferromagnetic moment of 0.11(1). History. 1895.

For low energies and under conditions where the electron does not penetrate the nucleus, the electron scattering can be described by the Rutherford formula. The Rutherford formula is an analytic expression for the differential scattering cross section, and for a projectile charge of 1, it is. 6-x. Au. x. system hosts the first known example of an elastic quantum critical point. Neutron and x-ray diffraction measurements were performed to study the structural properties as a function of temperature and Au-composition. First principle calculations confirm that the phase transition is driven by an elastic instability and is independent of electronic properties. Heat capacity measurements indicate the presence of quantum fluctuations at the critical composition. . CD/DVD drive. Image top. : . http://en.wikipedia.org/wiki/File:Dismdvd.. jpg.
