Some typical SANS patterns

SANS patterns are often quite beautiful with a reminiscence of Vasareli art painting.

Why Neutrons?

  • No charge, very penetrating, and non destructive to samples
  • Neutron wavelengths are comparable to atomic sizes and inter-distance spacing
  • Neutron interactions with hydrogen and deuterium are widely different making the deuterium labeling method an advantage.
