Researchers have taken atomic diffraction to a new level, revealing surprising behaviors in high-energy helium and hydrogen atoms ... passing through a crystal grating produced diffraction ...

Q: What are diffraction gratings? A diffraction grating is an optical component for spectroscopy that splits light into different wavelengths. A typical diffraction grating has thousands of ...

The need for smaller grating periods and higher momentum transfer led researchers to crystalline materials. However, achieving atomic diffraction ... directed helium and hydrogen atoms ...

The solution was then cast on a holographic diffraction-grating master mould to obtain free-standing silk gratings with a grating pitch of 600 grooves per millimetre, as shown in Fig. 4.
