| Abstract: | The stopping powers and energy stragglings for implanted ions in strongly coupled degenerate electron gas were investigated using local-field correction dielectric function.The numerical results have shown thst the stopping powers and energy stragglings were considerably increased due to local-field correction at low volecities and high valuse rs. |

| Keywords: | stopping powers energy stragglings implanted ions material surface modification dielectric function |
