- Large-scale molecular dynamics computer simulations are used to investigate the dynamics of material ejection during high-energy $Ar_n$ cluster bombardment of Ag(111) at normal incidence. The silver sample containing 7 million atoms is bombarded with $Ar_n$ projectiles (n=45-30000) with kinetic energy spanning from a few keV up to 1 MeV. Such a wide range of projectile parameters allows probing processes taking place during low-density collision cascade as well as during high-density events characteristic of micrometeorite bombardment in space. The material modifications and total sputtering yield of ejected particles are investigated. While at low-energy impacts, ejection of individual silver atoms is the main emission channel, the ejection of large clusters from the corona of the created crater dominates for the high-energy impacts.
