Abstract
Phonon-like excitations of an anti-instanton-instanton liquid that are due to adiabatic variations in the instanton dimension are considered on the ba sis of an approximate calculation of the relevant path integral, which is s aturated by quasizero modes. The kinetic term and the effective Lagrangian are found for such excitations. The properties of their spectrum, which has a mass gap determined by Lambda(QCD), are discussed.
