π-, K-mesons and protons resulting spectra and nuclear modification factors measured in p+p, Cu+Cu and Au+Au collisions at √S[NN] = 62.4 GeV have been presented. Comparison with nuclear modification factors measured for π-mesons and protons in Cu+Cu and Au+Au collisions at √S[NN] = 62.4 GeV was carried out. The domination of jet-quenching effect over Cronin effect was shown to happen in the energy range between 22.4 and 62.4 GeV.
