Dimensional Scaling Techniques Applied to Excited States of Atoms (Physics)

在基本粒子理论中成功应用的尺度标度方法应用于原子物理问题。在束缚态问题上的应用表明，该方法和其他微扰理论一样，在原子物理学中有作为定量工具的潜力。这里预期的应用是涉及He的双激发态的问题。这些状态是自电离的，这将是第一次将1/D展开应用于连续统问题。该方法的优点是它比其他方法更容易处理粒子的集体运动。这对于准确描述和的激发态是很重要的。

The dimensional scaling approach used successfully in elementary particle theory is applied to problems in atomic physics. Applications already made to bound state problems suggest that the method, like other perturbation theories, has some potential as a quantitative tool in atomic physics. The applications anticipated here are to problems involving the doubly excited states of He. These states are autoionizing and the work would be the first such application of the 1/D expansion to the continuum problem. The method has the advantage that it treats collective motion of the particles much more easily than other approaches. This is important for an accurate description of the excited states of He.
