They shared their results with Austrian physicists Otto Frisch and Lise Meitner, who termed the phenomenon “nuclear fission.” Columbia physicists rushed to replicate the experiment using the cyclotron in Pupin Hall.

A team of scientists including Dunning, Herbert Anderson, Eugene Booth, and Francis Slack were the first Americans to split the uranium atom and demonstrate the enormous release of energy that resulted.

Rabi and Enrico Fermi, joined Columbia’s research team to investigate the relatively new science of atomic particles.

Hungarian physicist Leo Szilard first realized the possibility of a nuclear chain reaction in 1933, and against the backdrop of escalating hostilties in Europe, the race began to harness the enormous energy within the atom.

An atom trapping device has has been developed by the group at Columbia University to do exactly that (see E. The device is calibrated carefully in order to find the trapping efficiency, i.e.

The results of such experiments provided valuable clues about the behavior of atoms.

Multiplying the measured loading rate for a given sample by the known trapping efficiency gives the total number of krypton atoms flowing through the system.

Finally, measuring how many xenon atoms flow through the system at the same time allows the krypton fraction to be calculated.

Important Manhattan Project research was conducted at Columbia University’s Pupin Hall (right) and Schermerhorn Hall.

World-class physicists, including Nobel Prize winners Isidor I.The following year, Columbia scientists first proved that the fissionable material in uranium that released energy when bombarded with neutrons was the isotope uranium-235.
