包括$m α^6$校正的氦能级

Helium energy levels including $m α^6$ corrections

Krzysztof Pachucki

摘要:

对于氦的任意态,$m α^6$对能量的修正用有效哈密顿量$H^{(6)}$表示。对$n=2$能级进行了数值计算,修正了以前对$2^3P$质心的计算结果。虽然由此产生的电离能的理论预测与实验值的$2^3S_1$,$2^3P$,和$2^1S_0$状态,他们是在单重态$2^1P_1$的显着分歧。

英文摘要:

The $m α^6$ correction to energy is expressed in terms of an effective Hamiltonian $H^{(6)}$ for an arbitrary state of helium. Numerical calculations are performed for $n=2$ levels, and the previous result for the $2^3P$ centroid is corrected. While the resulting theoretical predictions for the ionization energy are in moderate agreement with experimental values for $2^3S_1$, $2^3P$, and $2^1S_0$ states, they are in significant disagreement for the singlet state $2^1P_1$.
