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, ...

A photon is absorbed by the ground state of helium-4. This excites the transition to the first excited state of helium-4, which sits just above the energy threshold for separation into a proton and a ...

Alpha particle radioluminescence detection and imaging is an advanced optical technique that capitalises on the light emitted when alpha particles interact with air molecules. When alpha particles – ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Discover the fascinating process of radioactive decay, where unstable atoms transform, releasing energy in the form of alpha, beta, and gamma emissions.

From mysterious dark matter to the radioactive decay of atomic nuclei, the past 12 months have reiterated just how strange particle physics can be. When you purchase through links on our site, we may ...
