 The classical approach is unable to reproduce the correct character of bonding due to the deficiency of quantum-mechanical effects in the potential.

 From this, a description of defect structures by classical potentials looks promising.

 Qualitative and quantitative differences exist.
 First of all, a different pathway is suggested as the lowest energy path, which again might be attributed to the absence of quantum-mechanical effects in the classical interaction model.
 Secondly, the activation energy is overestimated by a factor of 2.4 compared to the more accurate quantum-mechanical methods and experimental findings.

 This has been shown to have two reasons, i.e. the overestimated barrier of migration due to the artificial interaction cut-off on the one hand, and on the other hand the lack of quantum-mechanical effects which are crucial in the problem under study.
