Prediction of mechanical and radiation parameters of glasses with high Bi2O3 concentration
Results in Physics, 2021 This study aims to perform multidirectional characterizations on nuclear shielding efficiencies on some bismuth-based glasses. Accordingly, the γattenuation coefficients for xBi2O3-(75-x)B2O3–25Li2O (x = 0, 10, 20, 30, 40, 50, 60 the 70 mol%) were widely

Fitting Equation of K-Shell Cross Section of Mg and Fe Atoms [PDF]
مجلة التربية والعلم, 2013 : An analytical formalism is suggested to describe the K shell ionization cross section for two atomic elements Mg (z=12) and Fe (z=26) by electron impact. This study is essentially based on the analysis of the calculated K ionization cross section given
