Abstract

Investigation of the Implantation profile and average stopping depth of slow positrons in Magnesium Sulfide MgS

Highlights

  • Proportional with the incident electron energy, which influences the screening process of the orbital electrons by the atomic nucleus, lowering the Bremsstrahlung probability cross section, while the values of with Mackinely-Fashbach equation, are in good agreement with the compared values,and the cross section obtained by improved Rutherford equation,shows that the effect of recoiling term is the biggest in comparison to other correction factors

  • For the energy range (50-350)MeV for the same angles, by using the improved Rutherford equation .All these equation written with Visual Basic program 2012.By comparing the obtained results with the available one, we found that the factor
