Abstract: | The cooperative character of the instability in a chain with a convex interatomic potrntial is shown. The low-temperature thermodynamics of such a chain is investigated. The interaction between such chains as a cause of the phase transition accompanied by doubling the lattice period in TlHF2 is discussed. |
