Аннотация:Доклад был представлен на конференции 23 августа 2021. The formation of sputtered atoms signal during ejection from the surface of Ni (100) face is investigated using our MD codes. Atoms are splitted into three groups (proper, focused and overfocused). Atoms overfocused into selected spatial angle have initial ejection energy between 13 and 21 eV and are divided into two subgroups. The subgroups differ one from another in initial azimuthal angle and mechanisms of surface atom scattering.
