دراسة قدرة إيقاف البروتونات و جسيمات ألفا في بعض الأوساط المختلفة

Abstract EN

In this researcher , calculaed stopping power for protons and alpha particles through these particles passing in some atomic medium which are (U , Au , La) and some compound which are ( H2O, C10H8O4,C22H18O5N2) .

As well as that we have been calculated the stopping power for protons and alpha particles in these mediums absorber by insert effective charge and by programming these equations for stopping power depended on Matlab Language and using Curve Fitting Tool .

The results appear protons and alpha particles stopping power in these medium depend on the projectile energy and the absorber medium .

we get a good agreement with ( )1992(( Bichsel)( results for protons and alpha particles in atomic medium and with SRIM2003 results but there is small different in the low energy .

The results appear a good agreement with stopping power equations results for protons and alpha particles in ( H2O, C10H8O4,C22H18O5N2( .So we note a good agreement between theoretical results and the results we get by using Curve Fitting Tool at the energy over than 0.6 MeV for protons and over than 5 MeV for Alpha particle in all using medium.
