摘要：

The first measurements of phi meson production in Au-Au collisions at AGS energies are presented via the decay to K+K-. A measurement of the centrality dependence of the yield shows an increase similar to that seen for the K- with a spectral shape consistent with a relativistic Breit-Wigner distribution within the statistical errors of the I,resent data set. Future analysis using the full data set with 4 times the statistics will allow a more accurate determination of the yields, slopes and spectral shapes.
