Mass Composition of the Primary Cosmic Rays in the Energy Region 10¹⁴-10²⁰ eV in Anomalous Diffusion Model

We discuss the problem of cosmic ray mass composition variation in wide energy region 10^{14}-10^{20} eV. The mass composition predicted in the framework of recently developed anomalous diffusion model is tested using the results of CORSIKA calculations and experimental data on the depth of maximum of extensive air showers. We show that the model predictions for the mass composition are consistent with observations of different experiments.
