Atomic Heats of Copper, Silver, and Gold from 1°K to 5°K

Abstract: The atomic heats of copper, silver and gold have been determined in the temperature interval 1.0° to 5.0° K. The measured values can be described adequately by a linear plus a cubic term in temperature. Any deviations from this relationship are explainable in terms of inaccuracies in the presently accepted helium vapor pressure-temperature scale. In fact, it is shown that the temperature scale corrections, necessary to correct the data to the simple law given above, essentially agree with temperature scale cor… Show more

“…1 of reference 5). The decrease at high fields is not inconsistent with AzbePs formulation for this value of COT if we take tn*~1.5 wo, 10 but the anisotropy of the effect is surprisingly marked for a cubic monovalent metal such as copper.…”

“…No entanto, ao se considerar os elétrons de condução como um gás não degenerado, os resultados obtidos não foram compatíveis com o comportamento térmico observado. Apenas quando Sommerfeld considerou-os como um gás degenerado de férmions de spin 1/2, os resultados teóricos tornaram-se compatíveis com os experimentos [22].…”

“…22 A distribuição de Maxwell-Boltzmann (a = 0) descreve o comportamento da população média em um gás ideal não degenerado, a distribuição de Fermi-Dirac (a = 1), a população média em um gás ideal de férmions, e a distribuição de Bose-Einstein (a = −1), a população média em gases ideais de bósons não massivos (λ = 1) e massivos. 23 20 A observação da população deátomos de He 4 com momentum nulo foi realizada em 1982 [26].…”

“…The multiple phonons in a high-order process share the momentum transfer, and the mixing of q complicates the data analysis. For improved accuracy, we have adopted a Debye model in a calculation of the high-order contributions [6][7][8] using the known Debye temperature of 344 K determined from specific heat measurements [14]. The calculation is included in the data analysis as a correction term.…”
