Positron Properties: A Positron With Kinetic Energy 2.0kev
A positron is an antiparticle of an electron, meaning it has the same mass as an electron but opposite charge. Positrons are positively charged, while electrons are negatively charged. Positrons are also known as antielectrons.
Positrons have the same spin as electrons, which is 1/2. However, positrons have a different magnetic moment than electrons. The magnetic moment of a positron is opposite to that of an electron.
Positrons are not stable particles. They will eventually annihilate with an electron, producing two photons.
