Within this study we use methods such as spectral analysis that gives the spectral coefficient β, detrended fluctuations analysis that gives the scaling exponent α and the determination of Hurst exponent (H) to analyze the spatial series corresponding to the temperature factors of N, C-alpha, C and O atoms of 14 complexes of the chicken lysosyme. The mean values of the investigated parameters obtained for the 14 complexes are: β=1.779 ± 0.086, α=1.382 ± 0.009 and H=0.916. These values reveal long range correlation in atomic vibrations corresponding to the chicken lysozyme backbone.
