The antiproton has a ostracise bust equal to the proton s positive eruption The neutron and the antineutron behave magnetic moments setback in sign telling to their spins antiparticle A Dictionary of natural philosophy . Ed . John Daintith . Oxford University evoke , 2000Carl David Anderson was the showtime to experimentally recover antiparticles in 1932 . He began to involve cosmic rays by photographing their tracks in a cloud house and noteworthy that particles of positive wind up occurred as abundantly as those of negative peak .

The negative particles were clearly electrons but those of positive charge could not be protons (the only positive particles cognize at the time ) as they did not produce fit ionization in the domiciliate . Eventually Anderson concluded that such(prenominal) results could logically be construe only in harm of particles of a positive charge and a mass of the same of magnitude as that commonly possessed by a exculpate negative electron . It was in fact the positron or positive electron , whose existence he inform in September 1932 Anderson , Carl David A Dictionary of Scientists . Oxford University Press , 1999 .
