The corrections relate to the series truncation approximating the WKB phase integral inherent in the analytic approximation of the electron tunneling probability. The assumed approximation for the phase integral takes into account not only the zero and first order terms, present in the existing theory, but also the quadratic term. The expression for the total energy distribution, obtained on this basis, is in typical circumstances valid for field emission in the electron energy range of |e| ≦ 1.5 eV with respect to the Fermi energy. The accuracy of the approximations used is also discussed. \u0000 \u0000 \u0000 \u0000Unter der Voraussetzung, das die Feldemission des Metalls durch das Freie-Elektronen-Modell beschrieben wird, werden korrigierte Formeln fur die totale Energieverteilung, die Emissionsstromdichte und die Inversionstemperatur abgeleitet. Die Korrektion erfolgt durch entsprechendes Abbrechen einer Reihe, die das WKB-Phasenintegral approximiert, was immer mit einer analytischen Naherung der Tunnelwahrscheinlichkeit des Elektrons verbunden ist. Die Approximation des Phasenintegrals berucksichtigt nicht nur die Glieder nullter und erster Ordnung, wie in der existierenden Theorie, sondern auch das Glied zweiter Ordnung. Die so erzielte Formel fur die gesamte Energieverteilung gilt unter typischen Feldemissionsverhaltnissen im Bereich der relativ zur Fermi-Energie gemessenen Elektronenenergie |e| ≦ 1,5 eV. Die Genauigkeit der angewendeten Approximation wird eingehend diskutiert.","PeriodicalId":11087,"journal":{"name":"Day 1 Tue, January 11, 2022","volume":"80 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1986-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82138901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the slow atom, v ≪ vF (v and vF are the velocity of the projectile and the Fermi velocity, respectively), electrons have enough velocity for response, thus the atomic states are not well defined due to the screening effect and the electron exchange processes. By constructing the model Hamiltonian which describes such effects from first principles the stopping power at grazing incidence condition, especially for the Cs surface, is calculated. \u0000 \u0000 \u0000 \u0000Der Energieverlust langsamer Atome wird vom Standpunkt einer indirekten Anregung von niederenergetischen Elektronen–Loch-Paaren untersucht, d. h. die Anregungen von Elektronen–Loch-Paaren durch den ElektronenaustauschprozeB vom Metall zu den atomaren Zustanden des Projektils und umgekehrt. Fur langsame Atome, v ≪ vF (v und vF sind die Geschwindigkeiten des Projektils bzw. die Fermigeschwindigkeit) haben die Elektronen genugend Energie fur Response, somit sind die atomaren Zustande infolge des Abschirmeffekts und der Elektronenaustauschprozesse nicht gut definiert.
