ENTDECKUNG DER KERNSPALTUNG PDF

Ausstellung Museumsgeschichte , 1. Enrico Fermi hatte als Erster einen Versuchsaufbau erdacht, bei dem Atome mit Neutronen beschossen wurden. Diese Versuche faszinierten Lise Meitner. Das Uran war damals das schwerste bekannte Element im Periodensystem der Elemente. Fermi selbst hatte bereits behauptet, dies getan zu haben, das hatte die wissenschaftliche Gemeinde allerdings angezweifelt.

Experiments by Enrico Fermi, notably the irradiation of uranium with neutrons in , set the stage. They hypothesized that elements heavier than uranium — transuranium elements — were formed during bombardment. Meitner and Frisch realized that the uranium nucleus can be pictured as an electrically charged drop of liquid in accordance with the previously formulated drop model.

Capturing an extra neutron caused the nucleus to oscillate so much that it split into two fragments of roughly equal size and releasing a huge amount of energy in the process.
