摘要

计算了氦原子S、P、D和F态的非相对论能级。计算是基于“指数”展开的变分方法。研究了计算能级的收敛性与基函数数目N的关系。这允许我们声称获得的能量值(包括具有非零角动量的状态的值)精确到28-35位有效数字。

Nonrelativistic energy levels of the helium atom

The nonrelativistic energy levels of a helium atom are calculated for S , P , D and F states. The calculations are based on the variational method of "exponential" expansion. The convergence of the calculated energy levels is studied as a function of the number of basis functions N . This allows us to claim that the obtained energy values (including the values for the states with a nonzero angular momentum) are accurate up to 28-35 signiﬁcant digits.
