  1. \(\,{}^{138}{\bf{B}}{{\bf{a}}}^{+}|{{\bf{s}}}^{{\bf{B}}{{\bf{a}}}^{+}}=1/2,{{\bf{m}}}_{{\bf{s}}}^{{\bf{B}}{{\bf{a}}}^{+}}=-1/2\rangle \) + \(\,{}^{6}{\bf{L}}{\bf{i}}|{{\bf{f}}}^{{\bf{L}}{\bf{i}}}=1/2,{{\bf{m}}}_{{\bf{f}}}^{{\bf{L}}{\bf{i}}}=-1/2\rangle \). The presented errors equal the 1σ confidence interval of the fit. We can further assign an overall systematic error of 60 mG on \(\delta {B}_{0}^{{\rm{expt}}}\), including daily drifts and calibration uncertainties. We compare our measurements with an ABM and can assign four s-wave resonances \({B}_{0,{\rm{s}}}^{{\rm{theo}}}\) for \({a}_{{\rm{S}}}=0.236\,{R}_{4}\) and \({a}_{{\rm{T}}}=-0.053\,{R}_{4}\).
