摘要
采用二元泛函变分的方法 ,求出了氦原子及类氦离子Li+ ,Be+ + ,B+ + + ,C4 + ,N5+ ,O6+ 的基态能量与波函数 .结果表明 ,二元泛函变分法比一元泛函变分法得到的结果更接近实验值 .计算得到的氦原子及类氦离子基态能量值与实验值之差 ,比用一元泛函变分法得到的能量之差减小 7%～ 1 5% .
The method of dual functional calculus is adopted and ground state energy and wave function of helium aton and quasi_helium ion Li +,Be ++ ,B +++ ,C 4+ ,N 5+ ,O 6+ are obtained. The result of ground_state energy is nearly equal to the experimental result by using mono_functional calculus (the traditional method). And the difference between ground_state energy of helium atom and quasi_helium and the experimental result is reduced by a factor of 7%～15%.
