Neutron Larmor Diffraction for the Determination of Absolute Lattice Spacing
The Neutron Larmor diffraction method is applied for the first time to determine absolute lattice spacing of a Silicon powder and polycrystalline IN718 samples. The absolute value of lattice spacing can be measured to an accuracy of 7· 10A. However, absolute determination of the lattice parameter is limited by the quality of the reference specimen used. Absolute lattice spacing determined by La...
متن کاملAberration-corrected precession electron diffraction
Precession electron diffraction (PED) is a promising technique for collecting high quality diffraction patterns for rapid nanoscale structural characterization [1]. It is able to reduce dynamical scattering effects, improving the interpretability of diffraction intensities over those obtained by conventional electron diffraction techniques. When used on a microscope that can produce a fine prob...
متن کاملPrecession of Isolated Neutron Stars
I summarize the evidence for precession of isolated neutron stars and theoretical effort to understand the observations. I discuss factors that might set the precession period, describe constraints on the material properties of the crust, and conclude with a brief discussion of possible sources of stress that would deform a neutron star to the extent required.

متن کاملOn the alignment for precession electron diffraction.
Precession electron diffraction has seen a fast increase in its adoption as a technique for solving crystallographic structures as well as an alternative to conventional selected-area and converged-beam diffraction methods. One of the key issues of precession is the pivot point alignment, as a stationary apparent beam does not guarantee a fixed pivot point. A large precession tilt angle, along ...
