X-ray emission spectrasoft L lines.The L spectra of the elements 14 ≤ Z ≤ 22 were reinvestigated. Because of the limited energy resolution of the multilayer reflectors neither Ll and Lη nor Lα and Lβ 1 could be resolved. Nevertheless, the line Lβ 3,4 = L 1 M 2,3 was ...
X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10^-8 to 10^-12 metre. The passage of X-rays through materials, including biological tissue, can be recorded. Thus, analysis of X-ray i
X-ray Photoelectron Spectrometry (XPS) helps scientists understand the surface chemistry of materials, and it can used to explore nearly every element, with the exception of hydrogen and helium. By clicking on different elements on theXPS periodic tableon ourXPS Simplifiedwebpage, researchers can ob...

(Rieder et al., 2003). The typical sample field of view has a diameter of about 35mm. Concentrations are extracted from the X-ray spectra using the empirical method described inGellert et al. (2006). The areas of the characteristic peaks of each element are determined with a nonlinear ...
Quantitative x-ray spectrum analysis is performed by the intensity of the lines employing a crystal analyzer, scintillation and ionization counter, and coordinate plotter. All elements with atomic number Z9 (sometimes lighter elements) may be determined by x-ray spectrum analysis methods. Generally, ...
X-Ray Spectra Abstract J. HERWEG (Berichte der Deutschen Physikalischen Gesellschaft, Heft 1, 1914) using a crystal of gypsum, obtains by means of the photographic method the result that the α and β lines of the tungsten X-ray spectrum coincide with the α and β lines of the platinum ...
Lighter elements, such as hydrogen and helium, cannot be analyzed using this method. Moreover, the presence of overlapping X-ray lines from different elements can sometimes make interpretation of spectra challenging. This overlap occurs when two elements have characteristic X-ray lines with similar ...
空心原子x射线单离子产额报道了利用兰州重离子加速器国家实验室ECR离子源首次引出的全裸Ar离子和类氢,类氦,类锂Ar离子与Be固体表面相互作用形成的空心原子x射线实验测量结果.结果发现,同样条件下,由于K壳层电子的剥离,Ar的K-x射线单离子发射产额增加了5个量级,约为3 6×10 -3每原子;而当L壳层存在电子时,Ar的...
