Using data recorded by the CLEO-II detector at Cornell Electron Storage Ring (CESR), we report the first observation of a narrow state decaying into Xi(c)(+) pi(-). The state has mass difference M(Xi(c)(+) pi(-)) - M(Xi(c)(+)) of 178.2 +/- 0.5 + 1.0 MeV/c(2), and a width of <5.5 MeV/c(2) (90% confidence level limit). The most likely explanation of this new state is that it is the Xi*(0)(c), the J(p) = 3/2+ spin excitation of the Xi(c)(0) charmed baryon.
