原子核电四极矩与三轴形变参量γ的关系研究

摘要

Electric quadruple moment is an important parameter characterized by the deviation from the spherically symmetric of nuclear charge distribution and have intrinsic link with the nuclear deformation parameters. But the relationship between electric quadruple moment Q and axis symmetric deformation parameters β （or ε ） is only given. This article gets relationship between nuclear electric quadruple moment Q and the tri-axial deformation parameter T and discusses the results using nucleus surface＇s spherical harmonics expansion in spherical coordinates.%电四极矩是表征核电荷分布偏离球对称程度的重要参数,与核形变参量之间有着必然的联系。但一直以来只给出了电四极矩Q与轴对称形变参量β（或ε）之间的关系。文章从原子核表面在球坐标中用球谐函数展开式出发,导出了原子核电四极矩Q与三轴形变参量γ的关系,并对结果进行了讨论。
