An important part of physics research is examining why theoretical calculations and experimental results sometimes don't match. A recent experiment in Germany studied the helium-4 nucleus, also known ...

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 Axion Longitudinal Plasma Haloscope (ALPHA) experiment reached a milestone on February 24 with the successful installation of a Bluefors helium dilution fridge at the site of the experiment in ...
