摘要
本文用变分法计算出He基态能量为－77．55ev，与实验值－79．0ev比较，误差为1．84％，说明交分法是比较成功的．
Tge ground-state energg of helium atom Calculated by using the Variational method is- 77. 55ev.The relative error is 1. 84% Comparing With the experimental Value -77. 0ev Such a good result shous that the Variational method is Successful
