First observation of inelastic X-ray scattering from condensed (4)He using high energy resolution.

Recently, the suitability of inelastic X-ray scattering for the investigation of solid and fluid (4)He has been demonstrated. For the test experiments an energy resolution of the order of 10-15 meV was used at the backscattering spectrometer INELAX at the storage ring DORIS of DESY, Hamburg. Lattice excitations were observed for momentum transfers along the c axis of h.

Experimental evidence for the existence of non-nuclear maxima in the electron-density distribution of metallic beryllium. A comparative study of the maximum entropy method and the multipole refinement method.

The electron-density distribution (EDD) of metallic beryllium has been derived from the structure factors of Larsen & Hansen [(1984). Acta Cryst. B40, 169-179] using the maximum entropy method (MEM).

Elemental microanalysis of individual blood cells.

A scanning proton microprobe was used to study single red blood cells in freeze-dried, whole-blood specimens. Simultaneous collection of PIXE and of forward and backward scattered proton data provided information on the heavier elements (Z>27) and on the organic mass under investigation. The trace elemental spectrum of a red cell was found to be reproducible, and no elemental losses were observed during proton bombardment.

Microstructures of duplex (beta + gamma) silver-tin alloys.

The microstructures of (beta + gamma) silver-tin alloys are especially influenced by both homogenization temperature and subsequent heat treatment. When the alloy is cooled from homogenization temperatures above approximately 200 degrees C, lenticular regions of the ordered orthorhombic gamma phase precipitate from within the disordered h.c.
