electron impact spectrometry
electron impact spectrometry 双语例句
In the measurements, we took some pivotal measures, i. e., 1）by using Monte Carlo simulations, we took into account the effect of multiple scattering of incident electrons through thin samples, the effect of backscattering of incident electrons from substrates as well as the effect of bremsstrahlung photons produced by incident electrons bombarding thick substrates; 2 we made use of Rutherford backscattering spectrometry to determine the thin target thickness; 3 we performed the detection efficiency calibration of the Si detector in the lower energy region by using standard radioactive sources in combination with the bremsstrahlung spectrum of carbon thick-target by electron impact.
