Abstract
We have measured the yields of antiprotons in Au + Au interactions in the rapidity range 1.2 < y < 2.8 as a function of centrality using a b eam line spectrometer. The shapes of the invariant multiplicity distri butions at p(t) = 0 are used to explore the dynamics of antiproton pro duction and annihilation.
