Die vervollständigung des termschemas von Zn I mit hilfe einer hohlkathodenentladung

Abstract

Spectra of Zn I obtained with a specially designed hollow-cathode device show many lines corresponding to “forbidden transitions”. Analysing these transitions, it is possible to obtain the position of a number of hitherto unknown high-lying energy terms of the Zn I atom. “Allowed” transitions from these terms lead to spectral lines situated in the far infra-red, a direct measurement of which would cause considerable difficulties. Observing the forbidden transitions, it is sufficient to investigate only a very restricted spectral range in the near u.v. to obtain quite a number of F, G, H, J terms and also some further additional terms to already known series of the Triplet System of Zn I. At the end of this paper a critical discussion of the published wavelengths is presented.
