We provide a theoretical analysis of recently measured fusion cross sectionswhich show a surprising enhancement at low $E_\mathrm{c.m.}$ energies for thesystem $^{132}$Sn+$^{40}$Ca as compared to the more neutron-rich system$^{132}$Sn+$^{48}$Ca. Dynamic microscopic calculations are carried out on athree-dimensional lattice with a time-dependent density-constrained densityfunctional theory. There are no adjustable parameters, the only input is theSkyrme effective NN interaction. Heavy-ion potentials $V(R)$,coordinate-dependent mass parameters $M(R)$, and total fusion cross sections$\sigma(E_\mathrm{c.m.})$ are calculated for both systems. We are able toexplain the measured fusion enhancement in terms of the {\it narrower width} ofthe ion-ion potential for $^{132}$Sn+$^{40}$Ca, while the barrier heights andpositions are approximately the same in both systems.
