{anti p} and {anti {Lambda}} production in Si+Au collisions at the AGS

{anti {ital p}} and {anti {Lambda}} production in central Si + Au collisions has been measured by E589 at the BNL-AGS. Preliminary {ital m}{sub {perpendicular}} spectra are presented for {anti {ital p}}`s and {anti {Lambda}}`s. The {ital dn/dy} distribution for {anti {ital p}}`s is also presented. Based on the {anti {ital p}} and {anti {Lambda}} measurements, {anti {Lambda}}/{anti {ital p}} ratios are calculated in the rapidity range of 1.1-1.5.
