The ${{\mathit \Xi}_{{c}}^{'+}}$ and ${{\mathit \Xi}_{{c}}^{'0}}$ 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.
${{\mathit \Xi}_{{c}}^{'+}}$ MASS   $2578.2 \pm0.5$ MeV (S = 1.1)
 
${{\mathit \Xi}_{{c}}^{'+}}–{{\mathit \Xi}_{{c}}^{+}}$ MASS DIFFERENCE   $110.5 \pm0.4$ MeV 
 
${{\mathit \Xi}_{{c}}^{'+}}–{{\mathit \Xi}_{{c}}^{'0}}$ MASS DIFFERENCE   $-0.5 \pm0.6$ MeV 
 
The ${{\mathit \Xi}_{{c}}^{'+}}-{{\mathit \Xi}_{{c}}^{+}}$ mass difference is too small for any strong decay to occur.
