摘要
采用包含了两电子之间关联坐标的单参数试验波函数,应用变分法计算了氦原子和类氦离子的基态能量以及与坐标变量有关的各种物理量的期望值,数值计算的结果与实验值相当吻合,表明目前的简单解析的试探波函数比较正确地描述了基态双电子体系在全空间的运动.
The energy levels for the ground states of helium-like atom systems and the expectation values of other physical quantities related to the coordinate variables are calculated by virtue of the variational method and the one-parameter trial wave function which includes the correlation coordinate between the two electrons of helium-like atoms. The numerical results are in good agreement with the experimental data and the exact values. The calculated results indicate that the present simple analytical wave function describes correctly the motion of the ground-state two-electron system in full space.
