48. The high-energy oscillations above □40meV in Fig. 4 are believed to be an artifact due to the low count rate in that energy regime and the slightly higher background count rate for E>□40meV as compared to E<□-40meV in Fig. 3, combined with the mathematical Fourier-log procedure employed in the PHOENIX software used for data evaluation (Ref.).

50. In a recent molecular-dynamics simulation of the PDOS of Cu3-x Aux alloy NCs, a suppression of the low-E phonon bands relative to the high-E peak height and a blueshift of the high-E peak with increasing L 12 ordering was predicted by R. Meyer, Laurentian University, Sudbury, Canada (private communication).
