Precision spectroscopy of helium and related atomic systems continues to serve as a cornerstone of experimental and theoretical quantum physics, offering stringent tests of quantum electrodynamics and ...

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 ...

For the first time, researchers from the PRISMA + Cluster of Excellence have determined the charge radius of helium-3 and thus also the exact difference to the radius of helium-4. This precision ...
