摘要: Within the framework of the dynamical classical over-barrier model, the soft collisions between slow highly charged ions (SHCIs) Ar17+ and the large copper clusters under large impact parameters have been studied in this paper. We present the dominant mechanism of the electron transfer between SHCIs and a large metal cluster by computational simulation. The evolution of the occupation of projectile ions, KLx satellite lines, X-ray yields, Auger electron spectrum and scattering angles are provided.
