Quay Siegbahn
Kai Manne Börje Siegbahn (born April 20, 1918 in Lund , † July 20, 2007 in Ängelholm ) was a Swedish physicist and Nobel Prize winner .
Life
Kai Siegbahn was born as the second son of the Nobel laureate in physics Manne Siegbahn and his wife Karin Högbom. After attending grammar school in Uppsala, he studied physics , mathematics and chemistry at Uppsala University from 1936 to 1942 and received his doctorate in Stockholm in 1944 on the subject of "Studies in Beta Spectroscopy". From 1942 to 1951 he worked at the Nobel Institute for Physics - today's Manne Siegbahn Institute for Physics. In 1951 he became professor of physics at the Royal Technical University of Stockholm . In 1954 he moved to the chair at Uppsala University, which his father held until 1937. Siegbahn was a member of many associations, including the Royal Swedish Academy of Sciences and President of the International Union of Pure and Applied Physics (IUPAP).
As the founder of the magazine "Nuclear Instruments and Method" in 1956, as its editor, he exerted intensive influence on a clear, scientifically sound orientation of the content. He has thus created a stable network of partners and an international reputation beyond the national borders of Sweden. In 1965 he is the editor of the book "Alpha, Beta and Gamma Ray Spectroscopy" with articles and technical contributions by 77 recognized experts in radiation spectroscopy.
He married Anna Brita Rhedin on May 23, 1944 and had three children, Per (* 1945), Hans (* 1947, also Professor of Physics in Uppsala ) and Nils (* 1953).

Siegbahn worked in the field of atomic and molecular physics , nuclear physics , plasma physics and electron optics .
From the end of 1950 to the beginning of 1960 Siegbahn and others developed an important measurement method from the photoelectric effect known up to then . The decisive contribution was the development of an electron spectrometer with a previously unattained accuracy, which made it possible to assign the electrons released by X-rays from a material to their place of origin (type of atom and shell ). The result of the measurement is a chemical analysis of the composition of the tested material, from which the name ESCA (electron spectroscopy for chemical analysis) is derived. For this work he was awarded the Nobel Prize in Physics in 1981 "for his contribution to the development of high-resolution electron spectroscopy ".
