Seaborg and Frank Asaro )〕 〔(The Array of Contemporary American Physicists:Isadore Perlman )〕 〔(University of California:In Memoriam )〕 The National Academy of Sciences called Perlman "a world leader on the systematics of alpha decay".〔 He was also recognized for his research of nuclear structure of the heavy elements.〔 He was also noted for his isolation of Curium, 〔(New York Times: Outstanding Events of 1947, Isadore Perlman in isolating curium, the heaviest known chemical element and the most violently radioactive;By WALDEMAR KAEMPFFERT;December 28, 1947, )〕 〔(New York Times:Curium, Man-Made Element 96, Is Isolated in Visible Quantity; Chemists at City Session Hear of the Violently Radioactive Solid -- Photo of Glowing Salt Solution Is Displayed ELEMENT CURIUM VISIBLY ISOLATED;By WILLIAM L. LAURENCE;September 17, 1947, )〕 as well as for fission of tantalum, bismuth, lead, thallium and platinum. 〔(New York Times:Ratio of Elements in Stars Found To Vary -- Speedboat Design;September 14, 1947, )〕 Perlman discovered uses of radioactive iodine and phosphorus for medical purposes.〔 He played a key role in Manhattan Project's plutonium production.〔 ==Neutron activation analysis== He was also a top expert in the field of archaeometry. He pioneered high-precision methods of neutron activation analysis at the Lawrence Berkeley Laboratory in the US. Neutron activation analysis helps to determine the origin of ancient pottery and other artifacts through the analysis of the clay from which they were made. He was helped in the project by another noted scientist Frank Asaro. Second millennium BC pottery known as Cypriot Bichrome ware was one of the first archaeological projects that Perlman and Asaro undertook. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Isadore Perlman」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
