Electrons in Fluids: The Nature of Metal-Ammonia Solutions

Colloque Weyl I was convened in June 1963 at the Catholic University of Lille to commemorate one hundred years of the study of metal-ammonia solutions. This memorable event, which involved a "single-particle excitation", inspired Gerard Lepoutre to assemble an international group of physicists and chemists to discuss the nature of metal-ammonia solutions. Colloque Weyl II, which took 1969, was initiated as a place at Cornell Universtiy, Ithaca, N.Y. in June "cooperative interaction" between...
