New mirror for Helium scattering microscope
A Spanish research group has developed a material that would facilitate the construction of better microscopes based on Helium atom scattering. While Helium scattering has been known since the 1930's, the new material can be used to build a a mirror that reflects the atoms with a higher efficiency than previously possible.
