摘要：

A nonperturbative theory of anharmonic multiphonon decay of strong local vibrations in a crystal is developed, which predicts sharp acceleration of the process caused by cubic anharmonicity near characteristic amplitudes (typically A similar to 0.3 Angstrom). An experimental observation of such a process is reported: strong acceleration of two-phonon decay of Xe-2* quasi-molecules is found in solid xenon. (C) 1999 Elsevier Science B.V.
