摘要
The specific features of the energy spectrum of stationary quantum states responsible for the melting and softening of a polyatomic system are investigated. It follows from the first principles of the quantum mechanics and statistical physics that the melting temperature of small nanoparticles can exceed the melting temperature of a macroscopic sample of the same chemical composition. The dependence of the temperature range of the transition of the polyatomic system to a microscopically labile state on the number of atoms is determined.
