We report the observation of the Ξ*+c state decaying into Ξ0cπ+ with Ξ0c → ΛK̄0π+π- or ΛK- π+π+π-. We have observed 47 ± 11 candidate events for the Ξ*+c state and measured its mass to be 177.1 ± 0.5 ± 1.1 MeV/c2 above the Ξ0c mass. We have also measured the Ξ0c mass to be 2470.0 ± 2.8 ± 2.6 MeV/c2.
