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 ...

Physicists in France have measured the longest ever radioactive half-life - over twenty billion billion years - in a naturally occurring element that decays by emitting alpha-particles. Nőel Coron and ...

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.

What these two processes share is baked into the math of each. In fact, in that respect, they're nearly identical. They both involve some stuff (atoms or money) that is either growing or shrinking.

Deep under a mountain in Italy, researchers continue to push the boundaries of science with an experiment that could rewrite ...
