The Extension of the X-ray-Doublet Laws into the Field of Optics

摘要: Application of relativity formulas for x-ray doublets to ultra-violet spectra.— Evidence has been presented which indicates that many the strongest lines in hot spark spectra are due atoms stripped all valence electrons excepting one jumping between energy levels emits radiation. For L with but electron, Li(+), Be(2+), B(3+), C(4+), it is found frequency difference varies atomic number Z accordance formula Δν=K(Z-s)4, constant K being.365 regular series, and screening s decreasing from 2.02 Li(+) 1.86 C(4+). Other attributed three electrons, same holding giving values about 20 per cent greater. In case triplets, differences widest pairs give two or four agree well only one, five though tending be somewhat Similarly M triplets (K=.108) C N, were obtained slightly greater than corresponding lines. decrease 7.45 Na(+) 5.74 P(5+), O P series being larger; (widest pair triplets) (doublets) vary up 9. outer transitions 3d2-3d1, 4d2-4d1 4f2-4f1 come out close 10. irregular 2s 3s levels, law also holds, (sqrt[νs]-sqrt[νp]) increasing regularly not very greatly Z. All these facts shown what should expected according Bohr-Sommerfeld theory; quantitatively influence upon effective nuclear charge addition shells. New terms. The above relations enable value a given ionized atom predicted, led discovery an doublet at λ1240 N(5+), assignment following doublets: λ990 N(3+), λ1493 1744 N(+), λ789 λ658 O(4+), λ922 O(2+). These results us new method predicting determining state ionization emitting certain lines. Doublet extreme 2p2-2p1 terms B(3+) C(4+) measured by use special grating ten orders.
