WebJan 30, 2024 · Positrons have the exact same mass as an electron, but are positively-charged. There are two forms of beta decay: the emission of electrons, and the emission of positrons. Beta particles, which are 100 times more penetrating than alpha particles, can be stopped by household items like wood or an aluminum plate or sheet. http://large.stanford.edu/courses/2024/ph240/payzer1/

Webpositron, also called positive electron, 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). …
Web, the electron's antiparticle) collide. At low energies, the result of the collision is the annihilation of the electron and positron, and the creation of energetic photons : e− + e+ → γ + γ At high energies, other particles, such as B … WebThe main idea in making antimatter is just getting enough energy in a collision to allow the particles to be made.
