在球偶偶核计算的情况下，我们给出了扩展的Skyrme N_2LO赝势的发展。首先给出了能量密度泛函。然后，我们推导了平均场方程，并讨论了求解所得到的四阶微分方程解的数值方法以及解在原点处的行为。最后，讨论了这种N2LO相互作用的拟合过程，并提供了第一个参数化法。计算了典型的基态观测数据，并与实验数据进行了比较。
We present the development of the extended Skyrme N2LO pseudopotential in the case of spherical even-even nuclei calculations. The energy density functional is first presented. Then we derive the mean-field equations and discuss the numerical method used to solve the resulting fourth-order differential equation together with the behavior of the solutions at the origin. Finally, a fitting procedure for such an N2LO interaction is discussed and we provide a first parametrization. Typical ground-state observables are calculated and compared against experimental data.
