X-ray emission spectra/ X-ray intensity spectratransparent targets/ A0785 X-ray, gamma-ray instruments and techniquesA formula has been deduced for predicting x-ray spectra from transparent targets. Particular versatility arises from being able to choose the values of the incident and emission ...
ray interference to be observed are introduced. Secondly, the results are exemplified by introducing the θ/2θ scan, which is a major x-ray scattering technique in thin-film analysis. Thirdly, the θ/2θ diffraction pattern is used to out- line the factors that determine the intensity of ...
1925年,Hendrik Kramers和海森堡(Werner Heisenberg),基于对应原理,给出了Kramers–Heisenberg色散公式, Kramers–Heisenberg formula 1925年,海森堡发明了矩阵力学,对于原子光谱做了比较好的解释:海森堡从玻尔频率条件和Kramers色散理论看到了矩阵力学的端倪,运用对应原理将物理量写成无限维方矩阵,得到了量子化条件和谐振子能级...
and at the same time, measure the intensity of the characteristic X-ray, until the right time that the intensity do not rise with the increase or decrease of grinding time.

Based on the electron scattering model, the theories of electron scattering and the formulae proposed by the authors for calculating generated intensity, absorption and fluorescence correction of X-rays in multilayer films, the ratios of X-ray emitted intensity in multilayer films are calculated with...
XPS X-Ray Sources In XPS instruments, X-rays are generated by bombarding a metallic anode with high-energy electrons. The energy of the emitted X-rays depends on the anode material, and the beam intensity depends on the electron current striking the anode and its energy. ...
