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 ...

In alpha decay, this particle is emitted; for example, titanium-48 becomes calcium-44 if such decay occurs. The OMU team calculated the collision effect of high-energy accelerated protons and α ...

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

Scientists have found evidence of alpha particles at the surface of neutron-rich heavy nuclei, providing new insights into the structure of neutron stars, as well as the process of alpha decay.

Though scientists know that alpha decay results in the ejection of this alpha particle, after a century of study, they still don't know the exact details of how the alpha particle is formed before ...

The scientists registered 128 alpha-particle events over 5 days and found an unexpected line in the spectrum at 3.14 MeV – now attributed to bismuth-209 decay. The half-life was calculated to be (1.9 ...

Quantum tunnelling One way that protons and neutrons could interact in a nucleus is to bind together to form an alpha particle (essentially a helium-4 nucleus). In 1928 George Gamow showed that alpha ...

Alpha radiation is a stream of alpha particles emitted from unstable nuclei. An alpha particle is also a Helium-4 nucleus.

Poor energy resolution, the result of numerous liquid scintillation statistical processes and energy spectrum quench, precluded, in general positive alpha-particle isotopic identification.

Radioactive decay is ubiquitous. It occurs everywhere on Earth and throughout the universe. The most common forms occur when an unstable nucleus spits out an alpha particle, consisting of two neutrons ...

Types of radioactive decay An unstable nucleus can decay by emitting an alpha particle, a beta particle, or a gamma ray. Alpha particle ...
