【 摘 要 】

Synopsis The modified addidtivity formula [1] for homonuclear cluster is employed to calculate the elastic, total and ionization cross section of silver cluster form ionization threshold to 20 keV and is compared with available experimental data [2,3]. The absorption, polarization, exchange and correlation effects are introduced in an optical potential through SCOP formalism [4]. The elastic and total cross sections are reported for the first time.
