${{\boldsymbol \Lambda}{(2350)}}$ $I(J^P)$ = $0(9/2^{+})$

DAUM 1968 favors $\mathit J{}^{P} = 7/2{}^{-}$ or ${}^{}9/2{}^{+}$. BRICMAN 1970 favors ${}^{}9/2{}^{+}$. LASINSKI 1971 suggests three states in this region using a Pomeron + resonances model. There are now also three formation experiments from the College de France-Saclay group, DEBELLEFON 1977 , BACCARI 1977 , and DEBELLEFON 1978 , which find ${}^{}9/2{}^{+}$ in energy-dependent partial-wave analyses of ${{\overline{\mathit K}}}$ ${{\mathit N}}$ $\rightarrow$ ${{\mathit \Sigma}}{{\mathit \pi}}$ , ${{\mathit \Lambda}}{{\mathit \omega}}$ , and ${{\mathit N}}{{\overline{\mathit K}}}$ .
