The data of multi-particle production in s~(1/2) =130 AGeV Au+Au collisions (RHIC) are analyzed by two-source statistical model which was successfully applied in analyzing the data of multi-particle production in 158 AGeV Pb+Pb collisions (SPS). It is found that sources in RHIC are different from that in SPS which has a small and hot inner source surrounded by a larger and cooler outer source. The two sources in RHIC are identical. They have the same temperature, volume, particle density and other thermodynamic quantities. Besides, the results of two-source model are identical with that of single-source model (the total volume of the two sources equals the volume of single source). The
