We have measured two phonon-dispersion curves above 50meV in a superconducting (T~ = 33 K) single crystal of Lal.85Sro.tsCuO4. In the normal phase (T =45 K), we show that the A, mode compatible with the Raman A, g (425 cm -1) mode is weakly dispersive, falling from 53.7 meV at the zone center to abo
