The method is applied to literature results for the longitudinal phonon dispersion in several glass formers. The constant frequency scans are well fitted in terms of a Q-independent phonon damping depending exclusively on the frequency, in agreement with two recent theories of the boson peak. The method allows us to link the x-ray Brillouin scattering to the diffuse Umklapp scattering from the boson peak vibrations at higher momentum transfer on an absolute intensity scale.}, cin = {ICS-1 / Neutronenstreuung ; JCNS-1}, ddc = {530}, cid = {I:(DE-Juel1)ICS-1-20110106 / I:(DE-Juel1)JCNS-1-20110106}, pnm = {451 - Soft Matter Composites (POF2-451) / 54G - JCNS (POF2-54G24)}, pid = {G:(DE-HGF)POF2-451 / G:(DE-HGF)POF2-54G24}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000349308700002}, doi = {10.1103/PhysRevE.90.062319}, url = {https://juser.fz-juelich.de/record/201688}, }
