Solution of the Skyrme HF+BCS equation on a 3D mesh

Abstract Over the years, the ev8 code has been a very useful tool for the study of nuclear mean-field theory. Its main characteristic is that it solves the Hartree-Fock plus BCS equations for Skyrme type functionals via a discretization of the individual wave-functions on a three-dimensional Cartesian mesh. This allows maximal flexibility in the determination of the nuclear shape by the variational process. For instance, the same mesh can be used to describe the oblate deformed, spherical, prolate def...

摘要
多年来，ev8程序代码一直是核平均场理论（nuclear mean-field theory）研究领域极具实用价值的工具。其核心特性在于，通过在三维笛卡尔网格（three-dimensional Cartesian mesh）上对单体波函数进行离散化处理，该程序可求解适用于Skyrme型泛函（Skyrme type functionals）的哈特里-福克加BCS（Hartree-Fock plus BCS）方程组。这使得变分过程在确定原子核形状时具备极高的灵活性。例如，同一网格可用于描述扁球形、球形、长球形等（oblate deformed, spherical, prolate def...）多种核形状。
程序名称：EV8

问题本质
本程序借助基于Skyrme型泛函的哈特里-福克加BCS方法，可通过最通用的四极约束条件确定多种核形状，进而研究偶偶核（even-even nuclei）结合能的演化规律。
