On the Relation between the Energy Levels of the Valence Electrons in Cu and Its Anomalous Temperatures

Abstract:

The absolute temperature is a measure of energy, as was clarified by Lord Kelvin. Hence, it was inferred that the interval rule existing in the anomalous temperatures of Cu, i.e., (0°K_??_230°C):(230°_??_550°)=3:2 and (0°K_??_277°C); (277°_??_1083° m. p.)=2:3, is no other than the Landé's interval rule of the fine structure of atomic spectra, saying that the interval ratio for the term of odd multiplicity, is equal to a ratio of a sequence of natural numbers. Accordingly, the anormalous temperatures of Cu, including 0°K, namely 0°K, 277°C, 1083° m. p. and 0°K, 230°C, 550° correspond to the components of E1 and E2, respectively, which were already determined from X-ray spectrum; the anmalous temperatures corresponding to E3 and E4, are expectable to exist in a range of low temperature.
