摘要：

The evolution of the Boson heat capacity peak in a typical metallic glass upon structural relaxation and partial crystallization is studied. It is found that heat treatment changes the peak height in both fully amorphous and partially crystalline states in line with the prediction of the Interstitialcy theory.
