on this project we try to calculated power of hydrogen on dycarbonil compound in different ways ; the first way is shoster way , for sain power of hydrogen notice the different power between central conforms on it and main conform that’s didn’t have hydrogen joint . or in other way different of energy between open and close form. second way, is average way? this is for way that studied conf...
An all-magnetic monochromator/spectrometer system for sub-30 meV energy-resolution electron energy-loss spectroscopy in the scanning transmission electron microscope is described. It will link the energy being selected by the monochromator to the energy being analysed by the spectrometer, without resorting to decelerating the electron beam. This will allow it to attain spectral energy stability...
Lattice images formed by plasmon energy-loss electrons in an energy-filtered transmission electron microscope are compared for different experimental parameters. The image resolution is primarily determined by chromatic aberration which is controlled by the width of the energy selection window. With an energy slit 3 eV in width, the plasmon loss electron image shows the same resolution and cont...
در این تحقیق اثر الکترونگاتیوی برای استخلاف های f, cl, no2 , cf3 برروی آروماتیسیته مولکول بنزن مورد مطالعه قرار گرفته است. nics, ase, homa, homo-lumo energy gapsشاخص هایی هستند که برای نمایش تاثیر استخلاف ها به کار برده می¬شوند.علاوه بر این الکترون های انتقالی توسط پیوند سیگما وپای نیز برای همه مولکول های استخلاف شده مورد نظر محاسبه شده¬اند.نتایج بدست آمده برای این روش ها با یکدیگر متفاوت است.ب...
Abstract A two-dimensional numerical simulation is performed in the present work to study the structure of a detonation wave in high activation energy mixtures, which are characterized by their turbulent reaction zone structure and unreacted pockets. The process of transverse wave and triple point collision with the channel walls, formation and consumption mechanism of unburnt gas pockets is e...
High Resolution E-ToF Mass Identification for Heavy Ions with Calorimetric Low Temperature Detectors
The direct in-flight mass determination of nuclides produced in heavy-ion induced reactions is an important task, requested in various fields of heavy-ion physics. It is in many cases mandatory for a unique identification of rare isotopes and an unambiguous interpretation of experimental data. The experimental technique often used for this purpose is a combined energy and time-of-flight (E-ToF)...
In this study, the effect of limited spatial resolution of hot wire anemometry (HWA) is investigated through analysis of the two dimensional energy spectra from direct numerical simulation (DNS) of turbulent channel flow at Reτ ≈ 934. Various spanwise filter lengths are applied to the streamwise velocity component in order to mimic the spatial resolution of the HWA experiments. The overall effe...
A novel wavelength dispersive soft X-ray emission spectrometer (WD-SXES) has been developed. It covers nominally the X-ray energy range between 50 and 210 eV [1, 2]. One of the characteristic features of the WD-SXES is parallel detection of the signal so that it can be used like a conventional energy dispersive spectrometer. One other feature is a high energy resolution, which is about 0.2 eV. ...
