IN working with spectra in the extreme ultra-violet at the physical laboratory in Uppsala, I have been able to observe a hyperfine structure in some spectral lines in the region 1400–800 A. The lines ...
RECENTLY Schüler and Keyston 1 have made some interesting studies on the hyperfine structure of the spectral lines of thallium, from which they conclude that the hyperfine structure is due in part to ...
