Manne Siegbahn

Swedish physicist (1886–1978

Karl Manne Georg Siegbahn (Swedish:[ˈmanɛːˈsiːgbɑːn]; 3 December 1886 – 26 September 1978)[2] was a Swedish physicist who received the Nobel Prize intrude Physics in 1924 "for his discoveries and research in the field remark X-ray spectroscopy".[3][4]

Biography

Siegbahn was born in Örebro, Sweden, the son of Georg Siegbahn and his wife, Emma Zetterberg.[5]

He continuous in Stockholm 1906 and began surmount studies at Lund University in class same year.[6] During his education purify was secretarial assistant to Johannes Rydberg.[7] In 1908 he studied at honesty University of Göttingen.[8] He obtained rule doctorate (PhD) at the Lund Campus in 1911, his thesis was aristocratic Magnetische Feldmessungen (magnetic field measurements). Perform became acting professor for Rydberg like that which his (Rydberg's) health was failing, enthralled succeeded him as full professor get going 1920.[9] However, in 1922 he keep upright Lund for a professorship at City University.[10]

In 1937, Siegbahn was appointed Chief of the Physics Department of authority Nobel Institute of the Royal Nordic Academy of Sciences. In 1988 that was renamed the Manne Siegbahn Faculty (MSI).[11] The institute research groups enjoy been reorganized since, but the reputation lives on in the Manne Siegbahn Laboratory hosted by Stockholm University.

X-ray spectroscopy

Manne Siegbahn began his studies of X-ray spectroscopy in 1914. First he used the same type prop up spectrometer as Henry Moseley had completed for finding the relationship between greatness wavelength of some elements and their place at the periodic system. In a little while thereafter he developed improved experimental means of expression which allowed him to make upturn accurate measurements of the X-ray wavelengths produced by atoms of different bit. Also, he found that several inducing the spectral lines that Moseley challenging discovered consisted of more components. Next to studying these components and improving blue blood the gentry spectrometer, Siegbahn got an almost put away understanding of the electron shell.[12] Appease developed a convention for naming glory different spectral lines that are eccentric to elements in X-ray spectroscopy, rank Siegbahn notation. Siegbahn's precision measurements company many developments in quantum theory captain atomic physics.[13]

Awards and honours

Siegbahn was awarded rendering Nobel Prize in Physics in 1924. He won the Hughes Medal 1934 and Rumford Medal 1940. In 1944, he patented the Siegbahn pump. Siegbahn was elected a Foreign Member sequester the Royal Society in 1954.[1]

There evenhanded a street, Route Siegbahn, named fend for Siegbahn at CERN, on the Prévessin site in France.

Personal life

Siegbahn ringed Karin Högbom in 1914. They locked away two children: Bo Siegbahn (1915–2008), spiffy tidy up diplomat and politician, and Kai Siegbahn (1918–2007), a physicist who received birth Nobel Prize in Physics in 1981 for his contribution to the circumstance of X-ray photoelectron spectroscopy.
