Abstract
Production of the phi meson in central Si + Au collisions has been mea sured by E859 at the Brookhaven Alternating Gradient Synchrotron by se lecting events with identified K+K- pairs. The mass and width of the p hi, obtained from the invariant mass distribution of kaon pairs, are c onsistent with those of free phi mesons. The transverse mass and rapid ity distributions are presented. The inverse slope parameter for an ex ponential fit to the invariant transverse mass distribution is 179 +/- 10 +/- 17 MeV.
