Abstract

We present measurements from Brookhaven AGS Experiment 864 of neutron invariant multiplicity in [Formula Presented] GeV/c [Formula Presented] collisions. The measurements span a rapidity range from center of mass to beam rapidity [Formula Presented] and are presented as a function of event centrality. The results are compared with E864 measurements of proton invariant multiplicity and an average [Formula Presented] ratio at hadronic freeze-out of [Formula Presented] is determined for the rapidity range [Formula Presented] to [Formula Presented] We discuss briefly the implications of this ratio within a simple equilibrium model of the collision system.
