Abstract
Using the CLEO detector, we present a measurement of the mass of the charged charmed strange baryon Ξ+c and its neutral counterpart the Ξ0c. The Ξ+c is observed through its decay to Ξ-π+π+, and its mass is measured to be (2467±3±4) MeV. The isospin mass splitting of the Ξc system is found to be M(Ξ+c)-M(Ξ0c)=(-5±4±1)MeV.
