Recent CLEO results on charmed baryon spectroscopy

Using data recorded with the CLEO-II detector, we report on our studies of charmed baryon spectroscopy. Preliminary evidence is presented for the Ξ + ' c and Ξ o ' c states which are observed in the decay Ξ c ′ → Ξ c γ . Last summer we observed the Ξ c1 + charmed baryon and at this conference we presented the observation of its isospin partner, the Ξ c1 0 . The Ξ c1 are seen via the decay Ξ c1 → Ξ c * π , with Ξ c * → Ξ c π .
