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 ...

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 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.

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 ...

Sumitomo Heavy Industries, Ltd. invests in Alpha Fusion Inc., developer of Astatine based radiopharmaceuticals for Targeted Alpha Therapy ...

Scientists from an international collaboration 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 ...
