In this work, we analyze the elastic scattering angular distributions of the weakly bound projectile \(^{\varvec{6}}\) Li on a \(^{\varvec{100}}\) Mo target at incident laboratory energies of 17.5, 19.0, 21.5, 23.0, 25.0, and 28.0 MeV. The analysis is performed within the microscopic double-folding optical model framework. The sensitivity of the elastic-scattering cross sections to different effective nucleon–nucleon interactions, projectile density distributions, and normalization schemes is systematically investigated. Three classes of effective interactions are employed: the velocity-dependent São Paulo Potential version 2 (SPP2), the density-dependent Michigan-3-Yukawa (M3Y), and the Botswana-3-Yukawa (B3Y) interactions, with projectile densities described by harmonic oscillator (HO) and Dirac–Hartree–Bogoliubov (DHB) models (DDB3Y1HO, DDB3Y1DHB, DDM3Y1HO, and DDM3Y1DHB). Two fitting strategies are explored: fixing the real normalization factor \(\varvec{N}_{\varvec{R}}\) while varying the imaginary normalization factor \(\varvec{N}_{\varvec{I}}\) , and allowing both \(\varvec{N}_{\varvec{R}}\) and \(\varvec{N}_{\varvec{I}}\) to vary. The latter approach yields consistently improved agreement with the experimental data at all energies. A detailed energy-dependent analysis of the microscopic optical potential parameters was performed for the system to reveal the systematic trends that reflect the underlying characteristics of the potentials. It was found that the SPP2 potential system requires higher \(\varvec{N}_{\varvec{R}}\) values across the energy range considered compared to the M3Y-based potentials. Overall, all considered potentials reproduce the elastic-scattering data with comparable quality, confirming the robustness of the microscopic folding approach for the \(^{\varvec{6}}\) Li+ \(^{\varvec{100}}\) Mo system.
