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...

Title of program: EV8
Catalogue Id: ADWA_v1_0

Nature of problem
By means of the Hartree-Fock plus BCS method using Skyrme type functionals, ev8 allows a study of the evolution of the binding energy of even-even nuclei for various shapes determined by the most general quadrupole constraint.

摘要
多年来，ev8程序一直是核平均场理论研究领域极具实用价值的工具。其核心特性为：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，求解适用于Skyrme型泛函（Skyrme type functionals）的哈特里-福克（Hartree-Fock）加BCS方程组。该方案可借助变分过程（variational process）极大提升原子核形状确定的灵活性，例如，同一套网格可用于描述扁球形形变、球形、长球形形变……

程序名称：EV8

问题本质
采用基于Skyrme型泛函的哈特里-福克（Hartree-Fock）加BCS方法，ev8程序可通过最一般形式的四极约束所确定的多种形变形状，研究偶偶核（even-even nuclei）的结合能演化规律。
