For central collisions with impact parameters b<2.4 fm the Lambda production cross section is 7.6±2.2 mb. A calculation in which Lambda production occurs in the early stage of the collision qualitatively reproduces the results but underestimates the transverse momenta. An average Lambda polarization of -0.10±0.05 is observed. PACS numbers: 25.70 Bc J. W. Harris; A. Sandoval; Reinhard Stock; Herbert Ströbele; R. E. Renfordt; J. V. Geaga; H. G. Pugh; S Schroeder; K.
