摘要：

A periodical chain of n equal particles coupled by a pure quartic-power potential was found to contain self-localized anharmonic modes. It is shown that for n = 3 the system is integrable and separable. The missing constant of motion turns out to be a kind of quasi-momentum that makes the localization move along the chain.
