This paper reports the investigation of the reaction ${\pi }^{+}+d\to K+\pi +{\Lambda }^0+p_s$ at a bombarding energy of 7 GeV/c. A recent compilation of data concerning ${\pi }^{-}+p\to K+\pi +{\Lambda }^0$ showed a discrepancy in the decay $K^{*0\mathrm{}}\mathrm{}\left(890\right)\mathrm{}\to K^{+}+{\pi }^{-}$ and $K^0+{\pi }^0$. The discrepancy was that too few of the latter decay modes were observed as compared with isospin predictions. This paper reports further investigation which shows a considerably smaller discrepancy than that previously found. The previously noted discrepancy must have been in part produced by a low scanning efficiency. The characteristics of these reactions are in other respects very similar to those observed at lower energies. The $K^{*}\text{'}\mathrm{s}$ seem to be produced by natural-parity exchange.
