Siegbahn, Kai Manne

Born Apr. 20, 1918, in Lund. Swedish physicist. Son of K. M. G. Siegbahn.

K. M. Siegbahn graduated from the University of Uppsala in 1939 and was a staff member of the university from 1941 to 1943. Between 1944 and 1954 he was affiliated with the Royal Institute of Technology in Stockholm; from 1951 he was a professor at the institute. He became a professor at the University of Uppsala in 1954.

Siegbahn’s principal works deal with nuclear and photoelec-tron spectroscopy. He developed precision techniques for the study of beta-ray spectra by means of magnetic spectrometers, including double-focusing spectrometers, high-transmission spectrometers for determining the upper limit of beta-ray spectra, and lens spectrometers. Siegbahn has also worked on electromagnetic methods of isotope separation and on the use of electron microscopy in chemical analysis.
