The temperature dependence ofA s symmetry phonons in a Y2Ba4CuTO~5\_~ (J~0.18, Tc=93 K) superconductor have been investigated between 10 and 300 K by means of Raman scattering. The observed changes in frequency and line-width between Tc and 10 K for the CuO2-and BaO-plane oxygen modes are consistent
