摘要:

提出了一种求解Dirac方程有限基组的新方法。它解决了虚假状态的问题,因此,提高了基组计算的收敛性能。通过计算类氢离子的单圈自能修正,证明了该方法在由B样条构造的有限基组上的有效性。

英文摘要:

A new approach to finite basis sets for the Dirac equation is developed. It solves the problem of spurious states and, as a result, improves the convergence properties of basis set calculations. The efficiency of the method is demonstrated for finite basis sets constructed from B splines by calculating the one-loop self-energy correction for a hydrogenlike ion.
