Each of the possible final states is treated as a shallow bound state composed of both $n+{}^{7}\\mathrm{Li}$ and $n+{}^{7}\\mathrm{Li}^{*}$ (core excitation) configurations. The {\\it ab initio} variational Monte Carlo method is used to compute the asymptotic normalization coefficients of these bound states, which are then used to fix couplings in our EFT.
