# ${{\boldsymbol \Xi}_{{c}}^{'0}}$ $I(J^P)$ = $1/2(1/2^{+})$

The ${{\mathit \Xi}_{{c}}^{'0}}$ and ${{\mathit \Xi}_{{c}}^{'+}}$ presumably complete the SU(3) sextet whose other members are the ${{\mathit \Sigma}_{{c}}^{++}}$, ${{\mathit \Sigma}_{{c}}^{+}}$, ${{\mathit \Sigma}_{{c}}^{0}}$, and ${{\mathit \Omega}_{{c}}^{0}}$: see Fig.$~$3 in the note on Charmed Baryons. The quantum numbers given above come from this presumption but have not been measured.
 ${{\mathit \Xi}_{{c}}^{'0}}$ MASS $2579.2 \pm0.5$ MeV
 ${{\mathit \Xi}_{{c}}^{'0}}–{{\mathit \Xi}_{{c}}^{0}}$ MASS DIFFERENCE $108.3 \pm0.4$ MeV
The ${{\mathit \Xi}_{{c}}^{'0}}–{{\mathit \Xi}_{{c}}^{0}}$ mass difference is too small for any strong decay to occur.
