Kai M. Siegbahn

(Created prior to 1993)
  
Question: I would like to find any information on Kai M. Siegbahn and his 
work with the high-resolution electron spectroscopy.  He won the Nobel Prize 
for it in 1981.
---------------------------------------
I do not have any reasonable information of this sort.  You would 
be best served to go to the library and get a copy of his Nobel lecture.  
These are published in a number of places.  That would tell you about his 
work.  Kai developed x-ray photo-emission, a great technique to study the 
electronic structure of materials.  the technique currently has a resolution 
of less than 0.1 eV.  Many spin-off techniques have also been developed since 
then which also study unoccupied bands.  Kai is Swedish, they needed a Prize.
