For results published before 1974 (they are now obsolete), see our 1982 edition Physics Letters 111B 1 (1982). Not all analyses require this state. It is not required by the GOYAL 1977 analysis of ${{\mathit K}^{-}}$ ${{\mathit n}}$ $\rightarrow$ ${{\mathit \Sigma}{\mathit \pi}}$ nor by the GOPAL 1980 analysis of ${{\mathit K}^{-}}$ ${{\mathit n}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit n}}$ .
