Abstract

We report on baryon and antibaryon as well as K⁺ and K^- production cross sections measured in lead-lead collisions at 158GeV/c per nucleon. The presented data were taken at zero degree production angle with a minimum bias trigger. The measurements covered a wide range of rapidity 1.4 < y < 6.0. Using a simple thermodynamical and a coalescence model the temperature and the chemical potential of the particle source as well as the freeze-out radius of baryons and antibaryons have been deduced.
