Fragmentation of polyatomic organic molecules on the surface under the action of low-energy ions

A model of the excitation of collective vibrational states (excimoles) in molecular chains of ordered valence groups of the C-F and C-H types (contained in thin organic films) under the action of sliding ions whose velocity is less than the Bohr velocity is proposed. The probabilities of accumulation of several excimoles and fragmentation of molecular chains in relation to the velocity of initial ions and the structure of molecules are analyzed.
