1  CARROLL 1976 sees a total-cross-section bump with ($\mathit J$+1/2) $\Gamma _{{\mathrm {el}}}$ $/$ $\Gamma _{{\mathrm {total}}}$ = 0.06.
2  The main effect observed by LITCHFIELD 1974 is in the ${{\mathit \Lambda}}{{\mathit \pi}}$ final state; the ${{\overline{\mathit K}}}{{\mathit N}}$ and ${{\mathit \Sigma}}{{\mathit \pi}}$ couplings are estimated from a multichannel fit including total-cross-section data of LI 1973 .
