摘要：

The hypothesis of statistical production of J/psi mesons at hadronization is formulated and checked against experimental data. It explains in a natural way the observed scaling behavior of the J/psi to pion ratio at CERN SPS energies. Using the multiplicities of J/psi and eta mesons the hadronization temperature T-H approximate to 175 MeV is found, which agrees with the previous estimates of the temperature parameter based on the analysis of the hadron yield systematics.
