A Fibonacci chain is composed of oscillators with two different masses and its total (even) number of oscillators N is associated with Fibonacci numbers. The momentum autocorrelation function of a specific oscillator in the chain is shown to be combination of 1 + (N/2) cosines, their frequencies and amplitudes are calculated numerically for N ≤ 40. The momentum autocorrelation functions are illustrated for Fibonacci chains with N up to 176.
