دراسة تأثير سرعة القذيفة على قدرة الإيقاف الالكترونية للأوساط الذرية (0.2-1000)MeV بمدى طاقة (La,Sm,Er,Ta,Au,Pb,U)

Abstract

Conducted in this research theoritocal study to calculate the effect of the speed of the projectile on the ability of the stop electronic using the equation Port equation Beth is then calculated based on the impact of Parker in the velocities of the charged particles of heavy [ protons, alpha particles and heavy ions (C, O)] falling on the objectives of the atomic (La, Sm, Er, Ta, Au, Pb, U). theory that accounts for the ability to stop passers-by all shells in the atomic targets and vehicles carried over in energy (0.2-1000MeV). Mathematical methods were used in the calculation and programming of all the equations according to a program written in a language of Matlab to get the required theoretical results that have been clarified as graphs . It was knowing that the speed of the incident particle is inversely proportional to the ability of the stop whenever he increases the speed of the projectile carrying capacity electronic suspension gradually Vnlhz because when the speed (v = 0.5v0) the ability of the suspension, and what can be higher , but at increased speed (v = 10v0) note a decrease in any electronic stopping power. that the relationship between them , according to an inverse equation Port.
