Line profiles of the plasma broadened lines He I: 3188, 3889, and 5016 Å and He II: 3203, 4686 Å have been determined from measurements using a wall-stabilized quasistationary pulsed discharge as a plasma source of sufficient homogeneity. The profiles were recorded applying the rapid-scan technique to enable single-shot registration of the spectral data. Electron density values were obtained from plasma-refractivity measurements at two different wavelengths using rare gas ion-lasers as background light-sources. The electron density range in this experiment was (0.7 -1.2) · 1017 cm−3. Temperature values of pure helium plasmas resulted from absolute radiation measurements (line intensities of He II 3203 Å and 4686 Å), yielding ~ 4 · 104 K. In helium-hydrogen mixtures further used for plasma generation in the lower temperature region, temperature values could be estimated from the optically thick Balmer line Hα, yielding ~ 2 · 104 K.
Experimental line shapes and half-widths are compared with the theoretical predictions of several authors and with the results of previous measurements. In case of neutral helium lines experimental and theoretical values agree within experimental accuracy (10%), whereas for the He II-lines the measured line shapes deviate considerably from the theoretical predictions.
Translation of the Bible or any other text unavoidably involves a determination about its meaning. There have been different views of meaning from ancient times up to the present, and a particularly Enlightenment and Modernist view is that the meaning of a text amounts to whatever the original author of the text intended it to be. This article analyzes the authorial-intent view of meaning in comparison with other models of literary and legal interpretation. Texts are anchors to interpretation but are subject to individualized interpretations. It is texts that are translated, not intentions. The challenge to the translator is to negotiate the meaning of a text and try to choose the most salient and appropriate interpretation as a basis for bringing the text to a new audience through translation.
Abstract. The self-broadening of principal series lines of rubidium and the corresponding oscillator strengths have been measured using a steel absorption tube heated up in an electric furnace. The line profiles were obtained from absorption measurements using a grating spectrograph of high resolution in the temperature range of 340-490 ~ the number densities varied from 5 -1016 to 8 9 1017 cm-3. The half widths deduced from the absorption profiles disagree with the classical impact approximation based on dipole-dipole interaction but approach closely the asymptotic values of the quantum-mechanical Reinsberg theory and of the "short-range"-calculations of Presnyakov. Oscillator strengths for the higher series lines were evaluated from the spectra agreeing very well with the asymptotic n*-3-hydrogen-like slope of the values.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
