${{\boldsymbol \Xi}_{{c}}^{'0}}$

$I(J^P)$ = $1/2(1/2^{+})$ 
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.$~$5 in the “Quark Model” review. The quantum numbers given above come from this presumption but have not been measured.
${{\mathit \Xi}_{{c}}^{'0}}$ MASS   $2578.7 \pm0.5$ 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.
