摘要：
The heat capacity of isotopically enriched S-28 , Si-29, Si-30 samples has been measured in the temperature range between 4 and 100 K. The heat capacity of Si increases with isotopic mass. The values of the initial Debye temperature circle minus(D)(0) for the three isotopic varieties of silicon have been determined. Good agreement with the theoretical dependence of the heat capacity on isotopic mass has been found. (C) 2005 Elsevier Ltd. All rights reserved.
