ResumoWe study soft hadron production in relativistic heavy ion collisions in a wide range of reaction energy, 4.8 GeV sqrt{s_NN} \ge 200 GeV, we use continuity of particle yields and statistical parameters to predict the hadron production at sqrt{s_NN}=62.4 GeV, and obtain total yields of hadrons at sqrt{s_NN}=130 GeV. We consider, in depth, the pattern we uncover within the hadronization condition, and discuss possible mechanisms associated with the identified rapid change in system properties at sqrt{s_NN ^cr}. We propose that the chemically over-saturated 2+1 flavor hadron matter system undergoes a 1st order phase transition.
