Boson Peak and Superstructural Groups in Na2O-B2O3 Glasses
Table 1
Samples designation, nominal composition, and “real” composition of xNa2O-(100-)B2O3 ( is given in mol%) glasses as well as the velocity of transverse ultrasonic waves, . The velocities of transverse ultrasonic waves, , were obtained via the method of the piecewise-linear approximation of the corresponding data published in ref. [17].
