Since the discovery of radioactivity in the 19th century, humanity has been forced to reckon with an uncomfortable but sobering truth: much of the matter we find today will eventually decay away. This ...

Theoretical calculations predict a complex excited state (0+) for helium-4 (4He) at the 20.21 MeV energy level. This state involves a coupling of three cluster configurations: hydrogen-3 and a proton, ...

Scientists refer to atomic nuclei as “quantum many-body systems” because they are formed by many particles (nucleons, which include neutrons and protons) that interact with each other in complex ways.

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. If you want to probe the frontiers of fundamental physics, you have to ...

Protons can hold an elementary particle heavier than themselves. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Protons may have more "charm" ...

AT SOME point in our lives, most of us learn that atoms are comprised of three types of particle: neutrons, protons and electrons. Each has distinct properties. The electron and proton have opposite ...
