The magnitudes of volume integrals per interacting nucleon pair $J_R$ calculated from a compilation of ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ potentials vary between 100 and 500 MeV ${\mathrm{fm}}^3$. They are grouped in discrete branches with $J_R\mathrm{}\left(A\right)\mathrm{}$ smoothly increasing with decreasing target mass. Comparison with the results for lighter projectiles restricts the "physically meaningful" branches to those characterized by $J_R(A\ge 48)\le 270$ MeV ${\mathrm{fm}}^3$. (${}_{}{}^6{}_{}{}^{}\mathrm{Li},d$) reaction analyses yield the same fit qualities for ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ potentials of the different discrete families, but deduced spectroscopic factors jump (by factors of ∼3) when changing between successive families.

NUCLEAR REACTIONS ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ optical potential volume integrals compared with volume integrals for lighter projectiles, discussed discrete ambiguities in (${}_{}{}^6{}_{}{}^{}\mathrm{Li},d$) DWBA; target masses $A=16\mathrm{} \mathrm{to} 64$, $E\left({}_{}{}^6{}_{}{}^{}\mathrm{Li}\right)=30\mathrm{}$ MeV.
