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.

Alpha particles, also known as alpha radiation, are the star players in the game of alpha decay — here's everything you need to know.

Although bismuth-209 is commonly thought to be the heaviest stable isotope that exists in nature, theory suggests that it should be metastable and decay via alpha-particle emission to thallium-205.

In a study published in Physical Review Letters, scientists at GSI Helmholtzzentrum für Schwerionenforschung have discovered ...

An unstable nucleus can decay by the emitting an alpha particle to become more stable. Image caption, 2. An alpha particle is a “ball” of two protons and two neutrons.

One is alpha particle decay, wherein an atom releases a helium nucleus. Beta decay involves the emission of a proton or an electron. In gamma-decay, a gamma-ray photon is emitted.

Each alpha decay lowers the atomic number by two. For example, evidence for element-114 consisted of a chain of alpha particles that were all detected at the same location in the detector within a ...

Decay channels are the possible transformations a particle can undergo as it decays. When a particle decays, it does not break into smaller bits; its energy does. Even fundamental particles—so named ...

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 ...

This decay is extraordinarily uncommon—according to the Standard Model (SM) of particle physics, which describes particle ...
