Nanocluster dynamics by mutual grazing with overthermal velocities

Moscow University Physics Bulletin Aims and scope

Abstract

A theoretical model of the interaction of two molecules during their mutual grazing is developed. Both molecules in the model are considered to be constructed of identical regular chain-like substructures of diatomic fragments. It is shown that at mutual grazing velocities lower than the Bohr speed in these fragments, which serve as IR radiation antennas, simultaneously with the grazing (∼10−12 s) both excitation and the accumulation of low-energy collective vibrational states (eximoles) occur. Energy transport occurs from antennas to trap-bonds in the same molecules and the energy exchange between molecules leads to their simultaneous fragmentation. The probability functions of the considered processes are derived and investigated.
