The yields and the transverse-momentum distributions of pions, kaons, and antiprotons produced in the central region of p¯p collisions at √s =1.8 TeV at the Fermilab Tevatron collider have been measured up to a charged-particle pseudorapidity density of approximately 20. The average transverse momentum 〈$p_t$〉 as a function of 〈${\mathrm{dN}}_c$/dη〉 for all three types of particles is presented.
