First detected in 1932 in a cloud chamber divided in two by a lead barrier, two of these particles are produced with helium in the hydrogen fusion reaction.
First detected in 1932 in a cloud chamber divided in two by a lead barrier, two of these particles are produced with helium in the hydrogen fusion reaction. Other reactions that produce it are the decay of copper-64 into nickel-64 and the decay of a gamma ray. Carl David Anderson won the 1936 Nobel Prize for detecting it as predicted in the quantum-mechanical theory of electron motion of Paul Dirac, and it can be produced in beta decay rather than an electron. FTP, name this antiparticle of the electron.
