E917 has studied the systematics of baryon stopping, and the production of φ mesons, antilambdas, and antiprotons in Au+Au collisions at 6, 8, and 10.8 GeV/nucleon. These studies indicate that the colliding nuclei are not fully stopped, and that secondary interactions play a significant role in φ production. The large increase in the Λ/p̄ ratio from peripheral to central collisions remains unexplained by theory.
