本文从唯象的Λ-α相互作用位和12C、16O的独立α粒子模型波函数出发,采用折迭位方法,求出了Λ-12C、Λ-16O等效相互作用位的解析表示,在此基础上计算了超核13C、17O的低激发态能量和自旋轨道耦合效应所引起的13C第一激发态的能级劈裂,并对Λ-12C、Λ-16O等效相互作用位和13C、17O的有关问题进行了分析和讨论. 相似文献

Lattice Boltzmann Simulation of Sedimentation of a Single Charged Elastic Dumbbell in a Newtonian Fluid 下载免费PDF全文
Based on the lattice Boltzmann method, the sedimentations of elastic dumbbells with different charges in a Newtonian fluid under the same and different initial conditions are simulated. Due to the polarizing effects, there are Coulomb forces exerted on the charged elastic dumbbells during their sedimentations, which change their original motions significantly. All of the numerical results show that, if the charged elastic dumbbells are released at offset-centreline positions with zero velocity and settle under gravity, they fall down vertically off the centreline and their orientations tend to be the horizontal finally, and the distances apart from the centreline increase with the increasing charges of the elastic dumbbells. 相似文献
