Biography

Siegbahn was born in Lund, Sweden, son of Manne Siegbahn the 1924 physics Nobel Prize winner. Siegbahn earned his doctorate at the University of Stockholm in 1944. He was professor at the Royal Institute of Technology 1951–1954, and then professor of experimental physics at Uppsala University 1954–1984, which was the same chair his father had held. He shared the 1981 Nobel Prize in Physics with Nicolaas Bloembergen and Arthur Schawlow for their work in laser spectroscopy.[2]

Siegbahn obtained the Nobel Prize for developing the method of Electron Spectroscopy for Chemical Analysis (ESCA), now usually described as X-ray photoelectron spectroscopy (XPS). At the time of his death he was still active as a scientist at the Ångström Laboratory at Uppsala University.

Publications

Kai Siegbahn was one of the original editors of the Encyclopedia of Analytical Chemistry

gollark: Oh, ubqvian metaspace information extraction?
gollark: It gets JITed. Did you not know?
gollark: Compilers did that, not people, probably.
gollark: I'm actually always correct so yes.
gollark: Premature optimisation is bad, so avoid spending ages for dubiously useful speed gains. But really inefficient code in some contexts is also bad, so optimise tight loops, frequently called stuff and real time stuff.
