Ramsay, William & J. Norman Collie | “The Spectrum of the Radium Emanation”
First edition, the journal issue in original wrappers.
Chemist Sir William Ramsay’s (1852-1916) most important research was on the noble, or inert, gases. He was the first to isolate helium and discovered neon, krypton, xenon, and argon, the latter being the element for which he and John William Strutt, 3rd Baron Rayleigh, were awarded Nobel Prizes in 1905.
In his Nobel lecture Ramsay described on-going spectroscopic work on radium, begun in 1903: “Much work remains to be done on these emanations. In conjunction with Dr. Collie, my colleague, the spectrum of the radium emanation has been mapped. It resembles generally speaking those of the inert gases... It might then be an unstable member of the argon family; there is a vacant place for an element with atomic weight about 162”. Ramsay’s work with radium was not particularly fruitful, and this paper mainly deals with efforts to purify samples and obtain accurate readings.
