Ida noddack cuestiona los resultados de fermi

Ida Noddack Tacke (25 February in Wesel - ) was a German chemist and physicist.

With her husband Walter Noddack she discovered element 75 Rhenium. She correctly criticized Enrico Fermi's chemical proofs in his neutron bombardment experiments, from which he postulated that transuranic elements might have been produced, and which was widely accepted for a few years.

Her paper, "On Element 93" suggested a number of possibilities, centering around Fermi's failure to chemically eliminate all lighter than uranium elements in his proofs, rather than only down to lead. The paper is considered historically significant today not simply because she correctly pointed out the flaw in Fermi's chemical proof but because she suggested the possibility that "it is conceivable that the nucleus breaks up into several large fragments, which would of course be isotopes of known elements but would not be neighbors of the irradiated element." In so doing she presaged what would be
