Transverse momentum spectra of electrons from Au+Au collisions at sqrt[sNN] = 130 GeV have been measured at midrapidity by the PHENIX experiment at the Relativistic Heavy Ion Collider. The spectra show an excess above the background from photon conversions and light hadron decays. The electron signal is consistent with that expected from semileptonic decays of charm. The yield of the electron signal dNe/dy for pT>0.8 GeV/c is 0.025±0.004(stat)±0.010(syst) in central collisions, and the corresponding charm cross section is 380±60(stat)±200(syst) μb per binary nucleon-nucleon collision
