used to explore materials and processes in a very wide range of domains. In this study, a neutron beam was sent onto a cell containing methane in supercritical conditions at constant temperature T=200 ... pressure from a few bars up to kbars (the critical pressure is P=45 bar). The intensity of the neutron beam scattered by the sample was measured ...

chemistry and materials science, in particular porous materials. The monochromatic neutron beam and flexible beam geometry can be adapted to various sample shapes, sizes and scattering geometries. In the

Mainz University it served for detailed atomic spectroscopy at the RISIKO off-line radioactive ion beam facility. Thus, the most comprehensive atomic spectroscopy so far was performed for the element promethium ... calculations. En passant an efficient resonant laser ionization scheme was developed for radioactive ion beam facilities which opens a ...

microscopic scale. To look for these tiny droplets, Dr. Chiappisi aimed a neutron beam at samples of limoncello. “The neutron beam leaves the sample at a different angle, and this allows us to reconstruct what
