Abstract
The absorption spectrum of strontium vapour in the quartz ultra-violet and Schumann region has been obtained at good dispersion, leading to extension of the singlet principal series to n = 33 and discovery of 94 lines due to double-electron transitions, most of which are classifiable within six series converging on the Sr II 4 2D metastable term. Pronounced autoionization resonance effects occur in the Schumann region. We reclassify as 4d6p 3D° a triplet term previously listed as 4d6p 3F°.Keywords
