Recently measured fusion cross sections for the neutron-rich system ${}^{20}$O+${}^{12}$C are compared to dynamic, microscopic calculations using time-dependent density functional theory. The calculations are carried out on a three-dimensional lattice and performed both with and without a constraint on the density. The method has no adjustable parameters, and its only input is the Skyrme effective nucleon-nucleon interaction. While the microscopic density constrained time-dependent Hartree-Fock calculations lie closer to the experimental data than standard fusion systematics, they underpredict the experimental data significantly.
