WebFeb 23, 2024 · Abstract: The first theory of the rate and temperature dependence of nuclear fission reactions was put forward as early as 1939 by Niels Bohr and John A. Wheeler. Their theory uses a transition-state argument, well known especially to physical chemists, that was already being used to rationalise the temperature dependence of the … WebT he discovery of fission was a seed dropped on fertile ground.
