A team of physicists has shown that pairs of helium atoms, chilled to near absolute zero and launched into each other, can ...
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 ...
Helium atom precision measurements and calculations have a history of nearly a century. In the 1960s, theorists discovered that the fine-structure split (23P0-23P2) of the 23P energy level of helium ...
The interest in exotic atoms arises from the fact that they often facilitate the most basic experimental strategy used in physics: changing a single parameter or component in an otherwise complex ...
