تاثير الاضمحلال على قدرة ايقاف ايون الكاربون الساقط على الاهداف الصلبة (Au,C,Al) عند السرع الواطئة والعالية

Theoretical study is performed about effect of damping on the Stopping power for carbon ion incident on the solid target (Au, C, Al) at some low velocities (0.4,0.7,1) and some high velocities (13,16,19) a.u.. The Random Phase Approximation (RPA) and Plasmon-pole Approximation were dependent in the present work. A comparison is done on the stopping power under damping ( ) and when it ignored ( ). We fond that stopping power remains constant when the damping is neglected. But increases the stopping power under damping ( ).
