Ivar Waller
Ivar Waller (born June 11, 1898 in Flen , † April 12, 1991 in Uppsala ) was a Swedish physicist and crystallographer. He was a professor at Uppsala University .
Waller studied physics at Uppsala University with a licentiate degree in 1922 and a doctorate in 1925 ( theoretical studies of the interference and dispersion theory of X-rays ). Then he was a lecturer there and from 1934 until his retirement in 1964 professor of mechanics and mathematical physics.
He is best known for the Debye-Waller factor, for example in X-ray crystallography (together with Peter Debye ), which describes the thermal effect of lattice vibrations on scattering (at that time, the quantum mechanical theory of lattice vibrations was in particular by Max Born and Theodore von Kármán developed). It came from his dissertation in 1925.
He had been a member of the Royal Swedish Academy of Sciences since 1945 and was on the Nobel Committee for Physics from 1945 to 1972. In 1938 he became a member of the Royal Society of Sciences in Uppsala , in 1950 the Physiographical Society in Lund and in 1963 the Norwegian Academy of Sciences in Oslo . From 1947 to 1965 he was a member of the Swedish National Council for Nuclear Research and 1968/69 director of the Swedish state nuclear technology company AB Atomenergi . In 1965 he was awarded an honorary doctorate from the University of Leiden .
Per-Olov Löwdin was one of his students .
