Abstract
For the first time comparison of some properties of the low-energy vibrational excitations and the first sharp diffraction peak (FSDP) in glasses is carried out. It is found out that the position of low-frequency (boson) peak in Raman spectra correlates with the position of FSDP and changes of the boson peak intensity correlate with that of FSDP. These correlations confirm a connection of low-energy (2–10 meV) anomalies of vibrational spectra of glasses with characteristic length in their structure.
