英文摘要	The three-body force is indispensable in nuclear energy density functionals, which leads to a density-dependent two-body term in the Hartree-Fock approach. Usually, a single fractional power of density dependency is adopted. We consider the possibility of an additional higher-order density dependence in extended Skyrme forces. As a result, new extended Skyrme parametrizations based on the SLy4 force have been obtained and the improvements in descriptions of global nuclei have been demonstrated. The higher-order term can also substantially affect nuclear properties in the high-density region in general ways.
