This article by chemist Ida Noddack challenges physicist Enrico Fermi’s conclusion that his group had produced a synthetic transuranium element. The author provides chemical evidence to support her position and also criticizes Fermi’s lack of chemical analysis to support his claim. Noddack provides the first postulation of nuclear fission with the statement “When heavy nuclei are bombarded by neutrons, it is conceivable that the nucleus breaks into several large fragments, which would of course be isotopes of known elements but would not be neighbors of the irradiated element.” The article was translated from German to English by H. G. Graetzer.
