In LITCHFIELD 1971 , need for the state rests solely on a possibly inconsistent polarization measurement at 1.784 ${\mathrm {GeV/}}\mathit c$. HEMINGWAY 1975 does not require this state. GOPAL 1977 does not need it in either ${{\mathit N}}{{\overline{\mathit K}}}$ or ${{\mathit \Sigma}}{{\mathit \pi}}$ . With new ${{\mathit K}^{-}}{{\mathit n}}$ angular distributions included, DECLAIS 1977 sees it. However, this and other new data are included in GOPAL 1980 and the state is not required. BACCARI 1977 weakly supports it.
