WebThus for low temperatures, the heat capacity as well as the energies of Eq. (2) are essentially those of the harmonic oscillator. At higher temperatures, the quartic-like energies from the higher quantum numbers are contributing to the partition function and as a result the heat capacity, as indicated in Fig. 1, Webthe partition function and as a result the heat capacity, as indicated in Fig. 1, tends asymptotically to the limit of the quartic oscillator. The calculations above A = 0.2 show …
