${{\mathit \Lambda}{(2350)}}$

$I(J^P)$ = $0(9/2^{+})$ 
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 ${{\mathit N}}{{\overline{\mathit K}}}$.
