Chung-Yao Chao

Chao Chung- yao (Chinese赵忠尧/赵忠尧, Pinyin Zhao Zhongyao, W.-G. Chao Chung- yao; * June 27, 1902, † 28 May 1998) was a Chinese physicist.

Chung- Yao Chao studied the scattering of gamma rays in lead by pair creation in 1930, without knowing that positrons were involved in the anomalously high scattering cross section. When the positron was discovered in 1932 by Carl David Anderson, this confirmed the existence of Paul Dirac's antimatter what Chung- Yao Chao could explain previous experiments that gamma rays are emitted by electron-positron annihilation.

He joined the University of Nanjing in 1920 when he gained a Bachelor of Science in Physics in 1925. He then earned a Ph.D. degree in physics under the direction of Nobel laureate Robert Andrews Millikan at the California Institute of Technology in 1930. Later he returned to China and joined the Faculty of Physics at Tsinghua University in Beijing in.
