摘要：

The production and the observability of Lambda(1520), K-0(892) Phi and Delta(1232) hadron resonances in central Pb + Pb collisions at 160 A GeV is addressed. The rescattering probabilities of the resonance decay products in the evolution are studied. Strong changes in the reconstructable particle yields and spectra between chemical and thermal freeze-out are estimated. Abundances and spectra of reconstructable resonances are predicted.
