	Ida Noddack - Wikipedia, the free encyclopedia
		She and her husband looked for the then still unknown elements of the ordinal numbers 43 and 75 at the Physical Institute for Realm.
		Only the discovery of the rhenium was later confirmed, and the discovery of the element number 43 was doubted.
		This was finally discovered in 1937 and called Technetium, whereupon the name "Masurium" went into oblivion.

	JCE 2005 (82) 1309 [Sep] Some Footnotes on the History of Masurium
		I was very pleased to read the recent article by R. Zingales (1) about the history of element 43 which in notable parts comprises the twisted story of masurium from the announcement of its discovery (2) to its final acceptance more than seven decades later (3).
		As it may not be completely obvious from ref 1, it seems advisable to point out that the symbol “Ma” was quite firmly established in the chemical literature of the 1940s.
		The word “masurium” is misspelled throughout and element 75 (rhenium) is completely confused with element 72 (hafnium).

	E007: The Masurium File: An X-Ray Mystery (Site not responding. Last check: 2007-11-02)
		Walter Noddack, Ida Tacke and Otto Berg [1] reported the discovery of masurium and rhenium, elements 43 and 75, on the basis of weak lines in X-ray spectra excited by electron impact on fractions extracted from niobium and platinum ores.
		Ida Noddack-Tacke [5] published the first suggestion (for which she received little attention or credit) that Fermi's 'new elements' could be products of atomic fission and described how to prove it, five years before the idea was accepted.
		The stain on her reputation from the masurium affair is likely part of the reason, but by no means all, why her suggestion was disregarded.

		Masurium was recorded by clairvoyant observation in 1909 and discovered spectroscopically in 1931.
		The ovoids each contain 29 Anu, but in different atoms these vary in their arrangements, as shown in Fig.

	Ida Tacke and Nuclear Fission
		Tacke named it Masurium, but scientists outside Germany doubted her claim and rejected the name.
		Most scientists believed element 43 was so rare and it had such a short half-life, that it had probably disappeared off the face of the earth.
		Her husband chose Masurium for his homeland in eastern Prussia in what is now Poland.

		This element was later (1937) found by C. Perrier and E. Segre in a molybdenum foil irradiated in the Berkeley cyclotron, and named technetium.
		In a 1954 paper the authors write " in 1944 an important enrichment of masurium had been obtained, but then all preparations were lost and the work was interrupted for 5 years".
		It is not known if the enrichment of masurium was carried out in Strasbourg.

	C&EN: IT'S ELEMENTAL: THE PERIODIC TABLE - TECHNETIUM
		Little attention was paid to Ida Noddack-Tacke's article in 1935 questioning Enrico Fermi's claim that he discovered the transuranium element 93 (for which he received the Nobel Prize) and suggesting that his neutron bombardment of uranium may have resulted in the atoms disintegrating into fragments.
		Our calculation of the amount of element 43 required to produce their spectrum is very similar to the direct measurements of natural technetium abundance in uranium ore published in 1999 by Dave Curtis and colleagues at Los Alamos.
		As a participant in this scientific detective adventure, I'll always have a fondness for the "element that was discovered twice"--first as masurium, the first natural element discovered composed entirely of a spontaneous fission product; second as technetium, the first man-made chemical element.

	75 Rhenium (Site not responding. Last check: 2007-11-02)
		After three years research, element #75 was separated from gadolinite and named Rhenium (Latin for the River Rhine), after the Rheinland (Rhineland), the homeland of Ida Tacke (she was born in Lackhausen/Wesel).
		Therefore, some historians of chemistry consider that both names contain a large dosis of nationalism: the Rhine region and the Masurian swamps were during the First World War the most succesfull battle places for the German troops.
		Their discovery of Masurium was not confirmed (see Technetium).

		Using x-ray spectroscopy, they had reportedly discovered element 43, which they dubbed masurium.
		Ernest O. Lawrence, the Nobel Prize-winning physicist, called the masurium investigators "apparently deluded." In 1937 credit for the discovery of element 43 went to Carlo Perrier and Emilio Segre, who christened the substance technetium.
		But recent research has bolstered the masurium claim, inviting a close reexamination of the evidence.

	43 Technetium
		Noddack) and Otto Berg discovered element 75 in a sample of gadolinite (a basic silicate of beryllium, iron and lanthanides) and named it Rhenium.
		In 1925, Noddack, Tacke and Berg reported discovery of element Z=43, which they named Masurium, based on line identification of x-ray emission spectra from chemically concentrated residues of various U-rich minerals.
		Their results were disputed and eventually the discovery of element 43 (Technetium) was generally credited to Perrier and Segre, based on their chemical separation of neutron-irradiated molybdenum in 1937.

		The name was quite rightly given because it is the first element to be produced artificially.
		The element 'masurium' was erroneously reported as having been discovered in 1925.
		However, the element with the atomic number 43 was actually discovered by C. Perrier and E. Segré in 1937 when a smaple of molybdenum was bombarded with deuterons in the cyclotron of E.O. Lawrence in California.

	History of the Origin of the Chemical Elements and Their Discoverers
		In 1909, the element nipponium was claimed to be isolated from various minerals but the claim was never substantiated and it is now argued to be element 75 (rhenium) and not element 43 (technetium).
		Finally, in 1925, the element masurium was claimed to be found in platinum ores by Ida Noddack-Tacke, Walter Noddack and Otto Berg.
		They were not able to isolate weighable amounts of the element, so their claim was also never verified.

		Recently John Armstrong used a sophisticated X-ray database and spectral analysis software to simulate Tacke's team's 1925 data.
		He found that the spectral lines they attributed to Masurium appear consistent with element #43, supporting their earlier discovery.
		Additionally, it is now know that an isotope of element #43 occurs naturally in ores containing Uranium.

		If it did, it would be like the rest.
		It was once hoped to be masurium, discovered along with rhenium in 1924, but masurium turned out to be an illusion.
		Actually, Tc does occur in very small amounts as a fission fragment from the spontaneous fission of uranium, and some modern measurements with X-ray spectroscopy, the same method used by Tacke, have indeed detected it.
