Who Discovered Positron

By studying the tracks of cosmic ray particles in a cloud chamber, in 1932 Carl Anderson discovered a positively-charged particle with a mass seemingly equal to that of an electron. Carl Anderson’s particle was the first antiparticle proven by experiment and was named a “positron”.

Is positron and proton same?

Main Difference – Proton vs Positron A proton is a subatomic particle having a positive electrical charge (+1). A positron is also a positively charged subatomic particle. The main difference between proton and positron is that the mass of a proton is considerably higher than that of a positron.

Who discovered antiparticle?

The antiproton and antineutron were found by Emilio Segrè and Owen Chamberlain in 1955 at the University of California, Berkeley. Since then, the antiparticles of many other subatomic particles have been created in particle accelerator experiments.
