The dependence of the internal friction and Young's modulus on the oxygen deficiency in the superconductor YBa: Cu 3 07\_ ~ was studied at frequencies near 2. 7 kHz. Peaks observed near 110 and 230 K decreased with decreasing oxygen stoichiometry in a sample with the orthorhombic structure, and were
