Today (September 26, 1978) is the Memorial Day of Karl Manne Georg Siegbahn, winner of the Nobel Prize in Physics for his study of X-ray spectroscopy.
Karl Manne Georg Siegbahn was born on December 3, 1886, in Oripro, Sweden, the son of George Siegbahn and Emma Jeterberg. He graduated from Stockholm in 1906. In the same year, he began his studies at the University of Lund. During his education, he was assistant secretary to Johannes Ridberg. In 1908 he studied at the University of Cottingham. He received his doctorate in 1911 from the University of Lund. His dissertation was entitled Magnetic Feltmesungen (Magnetic Field Measurements). He became an acting professor when Reitberg was ill. And after him in 1920 was a full professor. However, in 1922 he left London to become a professor at Uppsala University.
In 1937, Siegbahn was appointed director of the physics department of the Nobel Institute of the Royal Swedish Academy of Sciences. In 1988 it was renamed the Mannequin Company (MSI). Institute research groups were restructured. But the name lives on in the Manne Siegbahn Laboratory run by the University of Stockholm. Manne Siegbahn began his study of X-ray spectroscopy in 1914. Initially, Henry Mosley used the same type of spectrometer to find the relationship between the wavelength of certain elements and their location over time. He then developed an advanced test machine. This allowed the X-ray wavelengths produced by the atoms of different components to be measured very accurately.
Furthermore, he found that many of the spectral lines that Mosley discovered contained more elements. By studying these components and improving the spectrometer, Seagan gained a complete understanding of the electron shell. He developed a conference for naming X-ray spectroscopy, different spectral lines characteristic of elements in the sequel code. Siegbahn’s accurate measurements sparked many advances in quantum theory and atomic physics.
Siegbahn was awarded the 1924 Nobel Prize in Physics for his discoveries and research in the field of X-ray spectroscopy. He won the Hughes Medal in 1934 and the Rumford Medal in 1940. In 1944, he patented the Seacon pump. Siegbahn was elected a Fellow of the Royal Society in 1954. Who discovered that electrons have a third envelope (M series) through the X-ray spectrum. Karl Manne Georg Siegbahn, the winner of the Nobel Prize in Physics for his X-ray spectroscopy studies, passed away on September 26, 1978, in Stockholm, Sweden at the age of 91.
