The influence of the clustering and charge-form-factor behavior of ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ on the properties of the $n$+Li system is investigated. By examining the $n$+${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ cross-section and phase-shift results, it is found that, in the low-energy region, a proper consideration of $n$+${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ cluster correlations in ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ is essential to explain the resonance structure, while in the high-energy region one must adopt in the calculation a ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ internal function which yields the empirical form-factor values over a wide $q^2$ range. Contributions from various nucleon-exchange terms are also studied. Here one finds that the main characteristics of these contributions do not seem to depend sensitively on the detailed nature of the cluster internal function.
