\i3)R30° determined by LEED: stable and metastable adsorption sites
It is found that the adsorption of potassium on Al(111) at 90 K and at 300 K both result in a C&f? X &)R30” structure. Through a detailed LEED analysis it is revealed that at 300 K the adatoms occupy substitutional sites and at 90 K the adatoms occupy on-top sites; both geometries have hitherto been considered as very unusual. The relationship between bond length and coordination is discussed w...
متن کاملSTRUCTURE OF THE Ag(ll0) SURFACE DETERMINED BY USING AVERAGED LEED INTENSITIES
The constant momentum transfer averaging method has been used to determine the surface structure of the Ag(ll0) surface. A contraction of 8% of the first layer spacing compared to the bulk value is found by comparing the shape of the averaged intensity profiles with kinematic calculations rather than the position of the peaks. This result agrees well with that obtained by a multiple scattering ...

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
15 صفحه اولSTRUCTURE DETERMINATION OF THE CLEAN Co(1120) SURFACE BY LEED
The atomic structure of the (1120) surface of cobalt has been determined by LEED using six intensity spectra at normal incidence. The surface exhibits the truncated bulk structure with a contraction of the first interlayer spacing by about 8.5% with respect to the bulk value. Quantitative evaluation of the LEED spectra was done using Zanazzi and Jona’s and Pendry’s r-factors. The minimum averag...
متن کاملNITROGEN ADSORPTION ON Re(OOO1) STUDIED BY LEED, TPD, AES AND ELS
The interaction of nitrogen with a Re(OOO1) surface has been studied by low energy electron diffraction (LEED), thermal desorption spectroscopy (TDS), Auger electron spectroscopy (AES) and electron energy loss spectroscopy (ELS). Two LEED patterns have been observed upon adsorption of nitrogen on Re(OOO1). One, identified as the 4 x 1, is induced by N, exposure at 115 K and is related to the or...
