氦原子的相对论能级

Relativistic Energy Levels of Para-Helium

R. Graebeldinger, P. Schust, M. Mattes, M. Sorg

摘要:

通过近似计算任意电荷数的类氦离子$z_{\rm ex} (2\le z_{\rm ex}\le 100)$的激发单重态$1s2s {}^1S_0$与基态$1s^2 {}^1S_0$之间的能量差,检验了相对论薛定谔理论的实用性.的结果进行比较,在文献中的其他理论方法和实验数据的相应预测。由于能量本征值问题的精确解是未知的,人们不得不求助于近似方法。然而,最粗糙的近似("球对称近似“)产生相对准确的结果,因此似乎值得开发更强大的近似技术

英文摘要:

The practical usefulness of Relativistic Schrödinger Theory (RST) is tested by calculating approximately the energy difference between the excited singlet state $1s2s {}^1S_0$ and the ground state $1s^2 {}^1S_0$ of the helium-like ions with arbitrary charge number $z_{\rm ex} (2\le z_{\rm ex}\le 100)$. The results are compared to the corresponding predictions of other theoretical approaches in the literature and to the experimental data. Since the exact solutions of the RST energy eigenvalue problem are unknown, one has to resort to approximative methods. However the crudest approximation (``spherically symmetric approximation'') yields relatively accurate results so that it seems worth while to develop more powerful approximation techniques
