It is argued that the contribution of quasi-localized 1D soft-mode vibrational excitations to the photon neutron Ž . quasi-elastic scattering QES correlated with the boson peak in glasses can be considerable, as well as the earlier revealed contribution of acoustic phonons is. The main points are th
