This paper presents a study on energy dependence of self-similar cascading rate of produced pions in nuclear collision in the entire accelerator energy 2.1A GeV-200A GeV using the results of F-moments methodology and Levy stable index in both pseudorapidity (η) space and azimuthal angle (ϕ) space. This analysis reveals a positive dependence of self-similar cascading rate on beam energy.
