Using a data sample of 980 fb(-1) of e(+)e(-) annihilation data taken with the Belle detector operating at the KEKB asymmetric-energy e(+)e(-) collider, we report the results of a study of excited Xi(c) states that decay, via the emission of photons and/or charged pions, into Xi(0)(c) or Xi(+)(c) ground state charmed-strange baryons. We present new measurements of the masses of all members of the Xi(0)(c), Xi(c)(2645), Xi(c)(2790), Xi(c)(2815), and Xi(c)(2980) isodoublets, measurements of the intrinsic widths of those that decay strongly, and evidence of previously unknown transitions.
