Abstract

Telah dilakukan perhitungan tampang lintang total hamburan dengan metode gelombang parsial. Dalam metode ini, besaran yang menjadi kunci adalah geser fasa δl diperoleh dengan menyelesaikan persamaan diferensial bagian radial hamburan kuantum dengan dan tanpa potensial penghambur. Perhitungan Numerik yang dipilih adalah metode Runge-Kutta karena kemudahan aplikasi dan akurasi tinggi. Potensial hamburan yang digunakan adalah potensial Coulomb tertirai (Screened-Coulomb) yang telah diketahui parameter-parameter potensialnya sebagaimana telah disajikan oleh Salvat (Salvat et al, 1987) melalui metode variasi medan konsisten. Hamburan yang dimaksud adalah hamburan elektron-atom.
