NANOSTAR U: (Bruker AXS)
The interaction with matter depends on the probe which one uses. In contrast to neutrons, which interact with the nuclei of the sample, xrays interact mainly with the electrons around the nuclei. Small angle xray scattering therefore is a useful method to investigate samples which display a weak contrast for neutrons but a strong contrast in the electron density for which neutrons are ineffective. The applications range from polymers to biology or liquids and are limited to the scattering vector range given by the wavelength of the xray. Powerful combinations arise if both neutron and xray scattering are applied to the same system, exploiting the full contrast program. The scattered beam contains 3dimensional information on the spatial structure.
