Time-Of-Flight ERDA for Depth Profiling of Light Elements
The time-of-flight elastic recoil detection analysis (TOF-ERDA) method is one of the ion beam analysis methods that is capable of analyzing light elements in a sample with excellent depth resolution. In this method, simultaneous measurements of recoil ion energy and time of flight are performed, and ion mass is evaluated. The energy of recoil ions is calculated from TOF, which gives better energy resolution than conventional Silicon semiconductor detectors (SSDs). TOF-ERDA is expected to be particularly applicable for the analysis of light elements in thin films. In this review, the principle of TOF-ERDA measurement and details of the measurement equipment along with the performance of the instrumentation, including depth resolution and measurement sensitivity, are described. Examples of TOF-ERDA analysis are presented with a focus on the results obtained from the measurement system developed by the author

Index to the AEC/ERDA/DOE Air Cleaning Conferences
A comprehensive index to the papers in the second through sixteenth AEC/ERDA/DOE Nuclear Air Cleaning Conference is discussed. The index will be published in early 1981 and will be designated as Volume 3 of the proceeding of the sixteenth conference. The index has three parts, a straight numeric tabulation, an author index, and a key word in context (KWIC) index. (JGB

Die doppelte Triade: Wotan – Loge – Erda/Wagner – Freud – Butler
Dieser Aufsatz unterzieht Richard Wagners Rheingold einer Relektüre, die sich auf die darin enthaltenen Momente moderner Konzepte hin-sichtlich Inhalt und Handhabung der gesanglichen Disposition konzentriert. Diese sind, erstens, die Destabilisierung des Ich-Begriffes und, zweitens, Freuds Konzept der drei Instanzen (Ich, Es und Über-Ich) die das Selbst beherrschen. Einen dritten Schwerpunkt macht Wagners Idee eines androgynen Systems jenseits des Dualismus von Männlichkeit/Weiblichkeit aus, wie es von Judith Butler beschrieben wird. Eine Analyse der dramatischen Funktion und Gesangspartien – in Hinblick auf die oben genannten Prämissen – der Charaktere Wotan, Loge und Erda soll dabei aufzeigen, ob und wie Richard Wagner, ein Musikdramatiker des 19. Jahrhunderts, als Protomodernist und somit als Wegbereiter der Moderne gewertet werden kann.This essay offers a reading of Richard Wagner’s Rhinegold as a work in which important tendencies of modernity are prefigured in the opera’s narratological and vocal dispositions. These tendencies are, first of all, the destabilization of an intact identity and, second, the Freudian-based concept of the three aspects of the psyche, the id, the ego, and the super-ego, which govern the individual self. A third focus is on Wagner’s ideas of an androgynous system beyond the dualism of maleness/femaleness, as described by Judith Butler. With these premises, an analysis of the opera’s dramatic function and vocal parts for the characters Wotan, Loge, and Erda shows whether Richard Wagner, as an author-composer of the late nineteenth century, can be regarded as a protomodernist and thus a pacesetter for modernity

THE DEPENDENCE OF STARK SPLITTING ON VIBRONIC LEVEL FOR ELECTRONIC SPECTRA OF MOLECULAR MIXED CRYSTALS
Author Institution: Ames Laboratory-ERDA and Department of Chemistry, Iowa State University; Department of Chemistry, Washington UniversityIt has been observed that the electric field (Stark) spectrum of an impurity in a molecular crystal can demonstrate a dependence upon the individual vibronic levels in the spectrum. These variations in splittings among different vibronic levels are directly related to a variation of the permanent dipole moment of the molecule from that presumed within the crude adiabatic approximation
