Career

Meanwhile it was in 1930 that together with Professor Robert Millikan he began the cosmic ray studies. It was during his study that he discovered unexpected particle tracks in his cloud chamber by taking photographs. He correctly interpreted them as having been created by a particle with the same mass as the electron, but with opposite electrical charge.

Career

In 1932, this discovery was finally validated by the theories of Paul Dirac and led to the discovery of the existence of positron. The discovery of positron was an important advancement in physics, as the positron was the first particle of antimatter to be discovered.

Career

Following year, together with Dr. Neddermeyer, he obtained the first direct proof that gamma rays from ThC’’ generate positrons in their passage through material substances. He shot gamma rays into other materials, which resulted in the creation of positron electron pairs.

Career

In 1933, he took up the position of Assistant Professorship in Physics, which he served for six years after which he was promoted to the position of Professor of Physics.

Career

In 1936, he was awarded Nobel Prize for his discovery of positron. He shared the same with Victor Franz Hess, who too had made an important discovery in cosmic radiation.
