Bond breaking and making in mixed clusters of fullerene and coronene molecules induced by keV-ion impact. | LitMetric

AI Article Synopsis

Article Abstract

We have performed classical molecular dynamics simulations of 3 keV Ar + (CH)(C) collisions where (,) = (3,2),(1,4),(9,4) and (2,11). The simulated mass spectra of covalently bound reaction products reproduce the main features of the corresponding experimental results reported by Domaracka , , 2018, , 15052-15060. The present results support their conclusion that molecular growth is mainly driven by knockout where individual atoms are promptly removed in Rutherford type scattering processes. The so formed highly reactive fragments may then bind with neighboring molecules in the clusters producing a rich variety of growth products extending up to sizes containing several hundreds of atoms, and here we show examples of such structures. In addition, knocked out atoms may be absorbed such that hydrogenated coronene and fullerene molecules are formed.
