Coherent inelastic neutron scattering measurements have been carried out on the high temperature superconductors Tl2CaBa2Cu2O8 (Tl-2122,Tc =107 K) and YBa2Cu3O7 (Y-123,Tc =92 K), at the Dhruva reactor at Trombay. The density of phonon states in Tl-2122 is enhanced at 6-17 meV and reduced at 40-70meV compared to that in Y-123.
