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, ...
