Alpha decay represents a fundamental mode of radioactive disintegration wherein an unstable nucleus emits an alpha particle—a tightly bound cluster of two protons and two neutrons. This process not ...

A surprising and rare particle decay has left scientists puzzled as kaons, particles made up of quarks, are decaying in ways that defy current physics models. Could this anomaly indicate the existence ...

It’s the rarest particle decay ever discovered. Scientists have clinched the case for a special type of decay of subatomic particles called kaons. Further study of the rare decay could reveal a ...

PASADENA, Calif.—In the biggest result of its kind in more than ten years, physicists have made the most sensitive measurements yet in a decades-long hunt for a hypothetical and rare process involving ...

Hairs on the toes of Mexican free-tailed bats light up under ultraviolet light, but the reason is unknown, Jason Bittel reported in “Mexican free-tailed bats’ toes glow in the dark” (SN: 8/28/24).

Alpha particle radioluminescence detection and imaging is an advanced optical technique that capitalises on the light emitted when alpha particles interact with air molecules. When alpha particles – ...

The detector array consists of plastic scintillator detectors, quadrant silicon detectors (QSD), double-sided silicon detectors (DSSD) and high-purity germanium (HPGe) detectors. Exotic nuclei near ...

Once in a very great while, an ephemeral particle called a kaon arises and then quickly decays away into three other obscure entities. Whether or not this happens in a particular way has very little ...
