Artificial atoms allow scientists to push the laws of physics to the limit, gaining insight into what we are familiar with already and what we are yet to discover. Researchers have now created a new ...

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 ...

In the Quantum Mixtures Lab of the National Institute of Optics (Cnr-Ino), a team of researchers from Cnr, the University of Florence and the European Laboratory for Non-linear Spectroscopy (LENS) ...

A newly devised nozzle fitted with a pinhole-sized capillary has allowed researchers to distribute helium atoms with X-ray-like waves on randomly shaped surfaces. The technique could power the ...

A recent experimental measurement has identified a significant discrepancy between theoretical predictions and the observed behavior of the helium-4 nucleus. The work of an international collaboration ...

Physicists have created the first-ever atomic vortex beam — a swirling tornado of atoms and molecules with mysterious properties that have yet to be understood. By sending a straight beam of helium ...

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 ...
