1  The two MARTIN 1977 values are from a T-matrix pole and from a Breit-Wigner fit.
2  A total cross-section bump with ($\mathit J$+1/2) $\Gamma _{{\mathrm {el}}}$ $/$ $\Gamma _{{\mathrm {total}}}$ = 0.30.
3  An ${\mathit S}{\mathrm -wave}$ Breit-Wigner fit to the threshold cross section with no background and errors statistical only.
