Neutral helium microscopy and atom optics constitute an innovative imaging paradigm that exploits low-energy, charge-neutral helium atoms to non-destructively investigate surface properties at the ...

Galactic cosmic rays (GCRs) are energetic particles traveling across the Galaxy as high-energy beams, and are a unique probe to explore the astrophysical particle accelerators and the interstellar ...

For the first time, and contrary to popular belief, scientists measured the vibrational structure of hydrogen and helium atoms by X-rays. The results disprove the misconception that it’s impossible to ...
