Abstract
We present measurements from Brookhaven AGS Experiment 864 of neutron invariant multiplicity in 11.5A GeVlc Au+Pb collisions. The measurements span a rapidity range from center of mass to beam rapidity (ybeam = 3.2) and are presented as a function of event centrality. The results are compared with E864 measurements of proton invariant multiplicity and an average n/p ratio at hadronic freeze-out of 1.19±.08 is determined for the rapidity range y = 1.6 to y = 2.4. We discuss briefly the implications of this ratio within a simple equilibrium model of the collision system.
