Electronvolt - Wikipedia
网页In physics, an electronvolt (symbol eV), also written electron-volt and electron volt, is the measure of an amount of kinetic energy gained by a single electron accelerating through an electric potential difference of one volt in vacuum.
Scientists detect a cosmic ray that’s almost as powerful as the ... - CNN
网页2023年11月23日 · The “Oh My God particle” detected more than 30 years ago was 320 exa-electron volts. For reference, 1 exa-electron volt equals 1 billion gigaelectron-volts, and 1 gigaelectron volt is...
Higgs boson: The 'God Particle' explained - Space.com
网页2024年4月10日 · The Higgs boson has a mass of 125 billion electron volts — meaning it is 130 times more massive than a proton , according to CERN. It is also chargeless with zero spin — a quantum mechanical...
NASA’s Fermi Detects Surprise Gamma-Ray Feature Beyond Our …
网页2024年1月11日 · The scientists combined 13 years of Fermi LAT observations of gamma rays above about 3 billion electron volts (GeV); for comparison, visible light has energies between about 2 and 3 electron volts. They removed all resolved and identified sources and stripped out the central plane of our Milky Way galaxy in …
