摘要：

We have measured the buckling, B-1g, phonon mode of optimally doped, de-twinned, YBa2Cu3O7-delta using inelastic X-ray scattering (IXS) at BL35XU of SPring-8. Measurements of this mode, which has atomic motion transverse to the Cu-O planes, serve to demonstrate some of the advantages of the unique two-dimensional (2-D) analyzer array at BL35. Analysis based on fitting the entire spectra simultaneously at 10 and 100 K shows that the buckling mode is rather broad in the middle of the zone (near (0.3 0 0)). We see a consistent softening of the mode at 10K as compared to 100K for all measured wave-vectors (h 0 0), and a q-dependent softening as zone center is approached. (C) 2008 Elsevier Ltd.
