  The current paper presents the second part of the study devoted to composites
formed by fullerene C60 and single-walled carbon nanotube ([C60-(4,4)] carbon
nanobud). The formation of composites is considered from the basic points
related to the atomic chemical reactivity of the fullerene molecule and carbon
nanotube. The barrier that governs the composites formation is determined in
terms of the coupling energy and is expanded over two contributions that
present the total energy of deformation of the composites' components and the
energy of covalent coupling . The computations were performed by using the AM1
semiempirical version of unrestricted broken symmetry Hartree-Fock approach.
