For the first time, physicists have watched a beam of positronium, a short‑lived atom made of an electron and its antimatter ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...

The program demonstrates properties of these waves, including diffraction and interference, using various experiments. It concludes with an overview of radar technology, illustrating how it tracks ...

The same phenomenon was later confirmed for neutrons, helium atoms, and even large molecules, making matter-wave diffraction ...

For the first time, researchers from Tokyo University of Science have observed wave-like interference patterns from ...

“Positronium is the simplest atom composed of equal-mass constituents, and until it self-annihilates, it behaves as a neutral ...
