He Zehui was born in Suzhou,China on March 5, 1914.She studied in the field of nuclear physics.From 1940 to 1943,she worked in Siemens Werner Werk,where she did her research of magnetics in the Weak Current Laboratory.In 1943,she joined the Institute of Nuclear Physics of K.W.I. in Heidelberg, Germany. Later on in her life on June 20, 2011, she die in Beijing, China.
During Zehui's time in Heidelberg, Germany, she made a great discovery. She had disocvered elastic collision. Elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. When she collaborated with Qian Sanqiang and two graduate students, they made the discovery of the ternary and quaternary fissions of heavy nuclei. In 1948, Zuhei served as research professor of physics at the Institute of Atomic Physics,Institute of Modern Physics,head of the department of Neutron Physics of the Institute of Atomic Energy,and more. Also she contributed to neutron physics and physics of nuclear fission,as well as training qualified scientists in these fields.During 1950s,she initiated in China the research and development of nuclear emulsions. Zehui was awarded by Academia Sinica, the first Award of the National Prize of Natural Sciences.In 1980, she was elected as the member of the Chinese Academy of Sciences.

Her discovery of elastic collisions impacted the world greatly. In reality, examples of elastic collisions are not part of our everyday experience. Some collisions between atoms in gases are examples of perfectly elastic collisions. However, there are some examples of collisions in mechanics where the energy lost can be negligible. These collisions can be considered elastic, even though they are not perfectly elastic. Collisions of rigid billiard balls or the balls in a Newton's cradle are two examples.
