Ed . John Daintith . Oxford University Press , 2000Carl David Anderson was the distinguish to experimentally discover antiparticles in 1932 . He began to study cosmic rays by photographing their tracks in a cloud chamber and famed that particles of positive charge occurred as abundantly as those of negative charge .

The negative particles were distinctly electrons but those of positive charge could non be protons (the barely positive particles known at the time ) as they did not produce sufficient ionization in the chamber . last Anderson concluded that such results could logically be interpreted scarcely in terms of particles of a positive charge and a mass of the same of order as that normally possess by a isolated negative electron . It was in fact the positron or positive electron , whose populace he announced in September 1932 Anderson , Carl David A Dictionary of Scientists . Oxford University Press , 1999 .
