# ${{\boldsymbol \Lambda}{(1890)}}$ $I(J^P)$ = $0(3/2^{+})$

For results published before 1974 (they are now obsolete), see our 1982 edition Physics Letters 111B 1 (1982). The $\mathit J{}^{P} = 3/2{}^{+}$ assignment is consistent with all available data (including polarization) and recent partial-wave analyses. The dominant inelastic modes remain unknown.
