  • Positron - Wikipedia
    The positron or antielectron is the particle with an electric charge of +1e, a spin of 1 2 (the same as the electron), and the same mass as an electron It is the antiparticle (antimatter counterpart) of the electron When a positron collides with an electron, annihilation occurs
  • Positron | Antimatter, Annihilation, Electron | Britannica
    positron, positively charged subatomic particle having the same mass and magnitude of charge as the electron and constituting the antiparticle of a negative electron The first of the antiparticles to be detected, positrons were discovered by Carl David Anderson in cloud-chamber studies of the composition of cosmic rays (1932)
  • 11. 4: Positron Emission - Chemistry LibreTexts
    A positron, also called an antielectron, is an exotic bit of matter, or more correctly, an example of antimatter A positron is the antimatter equivalent of an electron It has the mass of an electron, but it has a charge of +1 Positrons are formed when a proton sheds its positive charge and becomes a neutron, as shown below:
  • 11. 2: Introduction to Particle Physics - Physics LibreTexts
    A surprising result of this theory was the prediction of two energy states for each electron: One is associated with the electron, and the other is associated with another particle with the same mass of an electron but with a charge of \(e^+\) This particle is called the antielectron or positron The positron was discovered experimentally in
  • Antimatter - CERN
    At CERN, physicists make antimatter to study in experiments The starting point is the Antiproton Decelerator, which slows down antiprotons so that physicists can investigate their properties The Antiproton Decelerator (AD) is a unique machine that produces low-energy antiprotons for studies of antimatter, and “creates” antiatoms
  • ANTIELECTRON Definition Meaning - Merriam-Webster
    The meaning of ANTIELECTRON is positron
  • What is a Positron? | Definition and Charge of Positron - Vedantu
    A positron or antielectron is the antimatter counterpart to an electron A positron has the equal or same mass as an electron and a spin of 1 2, but it has an electrical charge of +1 When a positron collides with electron annihilation, it results in the production of two or more gamma-ray photons
  • Positron - Simple English Wikipedia, the free encyclopedia
    A positron (also called an antielectron) is the antimatter version of an electron It has the same mass and spin as an electron However, it has a positive electric charge , whereas an electron has a negative charge
  • Antielectron - (College Physics I – Introduction) - Fiveable
    An antielectron, also known as a positron, is the antimatter counterpart of an electron It has the same mass as an electron but carries a positive charge
  • Still making tracks: Eighty years of the positron - CERN
    Eighty years ago today, the journal Physical Review published a paper by physicist Carl Anderson announcing the discovery of the positron The positron is the antimatter counterpart of the electron The two particles have identical masses but opposite charges
