Alpha Particle - Wikipedia
The symbol for the alpha particle is α or and thus not all high-velocity helium nuclei are considered by all authors to be alpha particles. Subsequent study of the spectra of the resulting gas showed that it was helium and that the alpha particles were indeed the hypothesized helium ions. ... Read Article
