Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has ...

The interaction between solid matter and positron (the antiparticle of electron) has provided important insights across a variety of disciplines, including atomic physics, materials science, ...

Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.

Using a highly coherent positronium beam, the researchers observed clear diffraction patterns after transmission through a graphene film, confirming its wave-like behavior. One of the discoveries that ...

The introduction of PET scans that can image more than one radiotracer simultaneously could revolutionize oncology by ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the observation that matter behaves differently at the smallest scales. A key ...

Positron, the antiparticle of electron, has the same mass and charge as that of an electron but with the sign flipped for the charge. It is an attractive particle for scientists because the use of ...
