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, ...

The latest results from the Antihydrogen Laser Physics Apparatus (ALPHA) experiment at the CERN particle-physics laboratory in Geneva have confirmed that the electric charge of antihydrogen is indeed ...

This is an example track of an alpha particle (energy 15 MeV) from the test beam registered with the demonstrator detector mini-eTPC. Read-out electrodes of the detector are parallel to the X-Y plane, ...

It’s the rarest particle decay ever discovered. Scientists have clinched the case for a special type of decay of subatomic particles called kaons. Further study of the rare decay could reveal a ...

Once in a very great while, an ephemeral particle called a kaon arises and then quickly decays away into three other obscure entities. Whether or not this happens in a particular way has very little ...
