Study ofΞ*Resonances inK−nInteractions at 3.6 and 3.9 GeV/c

We report on observation of the isospin-½ ${\Xi }^{*}\mathrm{}\left(1530\right)\mathrm{}$ and ${\Xi }^{*}\mathrm{}\left(1830\right)\mathrm{}$ resonances in $K^{-}n$ interactions at 3.6 and 3.9 GeV/c and present results concerning the production and subsequent decay of the ${\Xi }^{*}\mathrm{}\left(1830\right)\mathrm{}$ into $\Xi \pi$, $\Xi \pi \pi$, and $\Lambda \overline{K}$. We have also searched for isospin-$\frac{3}{2}$ ${\Xi }^{*}$ resonances and found no strong evidence for the existence of such states. Upper limits on production cross sections for such a particle are presented.
