Physicists at UC Riverside have created molecular positronium, an entirely new object in the laboratory. Briefly stable, each molecule is made up of a pair of electrons and a pair of their ...

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 ...

Quantum physics overturned classical ideas by showing that matter behaves very differently at the smallest scales. One of its most surprising discoveries was wave-particle duality, the idea that ...

Most atoms are made from positively charged protons, neutral neutrons and negatively charged electrons. Positronium is an exotic atom composed of a single negative electron and a positively charged ...

A new measurement of the exotic “atom” — consisting of an electron and its antiparticle, a positron — disagrees with theoretical calculations, scientists report in the Aug. 14 Physical Review Letters.

A short-lived combination of an electron and an antielectron has been cooled with lasers to near absolute zero—a step toward tackling fundamental questions about matter and antimatter. A hot gas of ...

Positronium is a particle created when you bind together an electron and its antimatter counterpart, the positron. It doesn’t interact with other atoms in the way we would expect, and this discovery ...

Simultaneous scans: Positronium lifetime image (left) and standardized uptake value image (right) of a phantom containing tumour and adipose tissue samples, recorded using the Jagiellonian-PET scanner ...

Discover the latest articles and news in related subjects. The quenching signal would look the same whether it were due to Ps 2 formation or SEQ, because both of these mechanisms essentially convert ...

At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same time. Matter no longer behaves like solid objects moving along clear paths.
