Nicolais L. Guevara, Frank E Harris, Alexander V Turbiner

摘要:

本文提出了一个简单的七参数试探函数来描述锂原子的基态。它包括两个自旋函数。电子间距离以指数形式以及指数前因子出现,并且通过相对坐标空间中的数值积分来评估必要的能量矩阵元素。令人鼓舞的准确值的能量和尖点参数,以及一些期望值。

英文摘要:

A simple, seven-parameter trial function is proposed for a description of the ground state of the Lithium atom. It includes both spin functions. Inter-electronic distances appear in exponential form as well as in a pre-exponential factor, and the necessary energy matrix elements are evaluated by numerical integration in the space of the relative coordinates. Encouragingly accurate values of the energy and the cusp parameters as well as for some expectation values are obtained.
