The classical partition function is given by Z = ZN , where
Note that u→kBT at both limits, ε→0 and ε→ ∞
The quantum results are simple in the limit of an infinite potential barrier (ε→ ∞). in this limit, we have to discard all of the harmonic oscillator states with even values of n (which are associated with even wave functions; wave functions that do not vanish at the origin, q = 0).
