| 摘 要： | 将基态氦原子的波函数取作1s2和1s2s两个组态函数的叠加,利用组态相互作用方法解析计算了氦原子基态的非相对论能量.计算结果表明,考虑激发态1s2s与基态的相互作用,可以获得0.029 38Hartree的基态能量修正.本文的解析组态相互作用方法可作为量子力学教学的有益补充.

| Abstract: | The analytical configurationinteraction calculation for the ground state of Helium is performed over two con figuration states:ls2 and ls2s.The results show that a 0.02938 Hartree correction to the ground state energy is obtained by add i ng ls2s configuration state.This calcu lation is suitable for the course of undergraduate quantum mechanics. |
