Nobel Physics Prize to Bloembergen, Schawlow and Siegbahn

The 1981 Nobel prize in physics has been awarded to Nicolaas Bloembergen of Harvard University, Arthur L. Schawlow of Stanford University and Kai M. Siegbahn of Uppsala University. Bloembergen and Schawlow will receive half the prize “for their contribution to the development of laser spectroscopy.” The other half will go to Siegbahn “for his contribution to the development of high‐resolution electron spectroscopy.” The prize, to be awarded in Stockholm on 10 December, this year amounts to one million Swedish kroner (worth about $180 000).
