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 ...

To understand nuclear decay equations. How to measure the activity of radioactive sources. Spontaneously means that the process of radioactive decay can not be speeded up or slowed down by physical ...

Double beta decay research represents a pivotal field at the intersection of nuclear physics and particle physics, probing the fundamental nature of neutrinos and their role in the matter–antimatter ...

Researchers have observed a rare nuclear decay. Namely, the team measured low-kinetic-energy protons emitted after the beta decay of a neutron-rich nucleus beryllium-11. Researchers from the National ...

Left: “Mirror” nuclei lithium-8 and boron-8 undergo beta decay, then split into two alpha particles. Right: Radioactive ions from the ATLAS accelerator at Argonne National Laboratory are suspended in ...

The origin of xenon in the containment of Fukushima Daiichi 2 is currently considered to be spontaneous fission, a process of radioactive decay not involving any chain reaction. The origin of xenon in ...
