When an alpha particle hits the zinc sulphide screen on the detector, a flash of light is observed. Geiger and Marsden counted these flashes of light at different angles around the vacuum chamber ...

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in ...

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.

A recent experiment in Germany studied the helium-4 nucleus, also known as an alpha particle. Helium-4 consists of only two protons and two neutrons, making it relatively easy to describe using ...

In early 2023, scientists published a new measurement testing the strong nuclear force. The experiment involved the way an  alpha particle becomes excited. The study suggested a puzzle that ...

Scientists working at the Relativistic Heavy Ion Collider have announced that they have detected the heaviest known particle of antimatter to date - an anti-helium nucleus, or anti-alpha particle ...
