For 10 points identify these positively charged subatomic particles having the same mass and magnitude of charge as their counterpart, the electron.
They are emitted in the positive beta decay of proton-rich radioactive nuclei and though they are stable in a vacuum they will react rapidly with matter to form gamma radiation. First postulated by P.A.M. Dirac in 1930, they were discovered two years later by Carl Anderson, for which he won the Nobel Prize in 1936.
