WebMay 22, 2024 · The antiparticle of the electron is called the positron; it is identical to the electron except that it carries electrical and other charges of the opposite sign. When an electron collides with a positron, both particles can be totally annihilated, producing gamma ray photons. The positrons are positively charged (+1e), almost massless particles. WebApr 5, 2024 · Schwinger’s theory built its intuition on the earlier work of Hans Bethe (1906–2005), published after attending the Shelter Island conference the year before.
