This report concerns itself with the study of four- or five-body final states produced by the interaction of 4.48-GeV/c $K^{-}$ mesons on neutrons. The data result from a 372 000-picture exposure in the Argonne National Laboratory 30-in. deuterium-filled bubble chamber. The reactions studied include (1) $K^{-}n\to \Lambda {\pi }^{+}{\pi }^{-}{\pi }^{-}$, (2) $K^{-}n\to {\Sigma }^0{\pi }^{+}{\pi }^{-}{\pi }^{-}$, (3) $K^{-}n\to \Lambda {\pi }^{+}{\pi }^{-}{\pi }^{-}{\pi }^0$, (4) $K^{-}n\to \Lambda {\pi }^{+}{\pi }^{-}{\pi }^{-}\mathrm{MM}$, (5) $K^{-}n\to \Lambda {\pi }^{-}{K}^{+}{K}^{-}$, and (6) $K^{-}n\to \Lambda {\pi }^{-}{K}_L^0{K}_S^0$, where all the $\Lambda$ particles decayed visibly. Evidence is presented for the existence of the $\Sigma \mathrm{}\left(1640\right)\mathrm{}$ whose mass and width are 1642 ± 12 MeV/${\mathit{c}}^2$ and 55 ± 24 MeV/${\mathit{c}}^2$, respectively. The branching ratios are found to be consistent with an octet assignment. The $A_2$ data are presented and are compatible with $J^{\mathrm{PC}}=2^{++}$. In addition, the productions of ${\rho }^0$, $\omega$, and ${\phi }^0$ are discussed in conjunction with simultaneous ${\Sigma }^{-}\mathrm{}\left(1385\right)\mathrm{}$ production and the results are compared with quark-model predictions.
