Inelastic X-ray scattering (IXS) experiments of RTAl ( = La Ce, = Cu, Au) were carried out at 300 and 5.5 K. The spectra between LaCuAl and CeCuAl (LaAuAl and CeAuAl) are nearly identical at both temperatures except for temperature factors such as temperature dependence of Bose factor in IXS spectra and effect on thermal expansion. This means that no evident temperature dependence of IXS spectra was observed in CeTAl ( = Cu, Au).
