First results from ultrarelativistic 16O+Pb collisions at 200 GeV/nucleon are presented. The transverse energy ET in average central collisions is ≈ 75 GeV for the interval 2.2≤y≤3.8. A 16-fold convolution of the inelastic p+Au transverse energy spectrum, also measured at 200 GeV, reproduces the mean ET of 16O+Pb. The amount of nuclear stopping power appears to be high.
