摘要：

The X-ray Debye temperature, θM, was measured at liq. He, liq. N2 and room temperature for two diamond powders of industrial quality, having a mean particle size of 6μ and 780Å respectively. The results are compatible with θM{reversed tilde equals} 1880°K for the fine and θM{reversed tilde equals} 1500°K for the coarse powder. A slight decrease of θM at low temperatures is possible within the experimental errors. Because no use is made of the atomic scattering factor, the claim is not substantiated that previous results around 1500°K necessitate a revision of the scattering factor curve for carbon. © 1969.
