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

成功使用的尺寸缩放方法， 基本粒子理论应用于原子问题 物理学 已应用于束缚态问题 表明，该方法，像其他微扰理论， 作为原子物理学定量工具的潜力。 的 这里预期的应用程序涉及的问题 他的双重兴奋状态。这些状态是自电离的， 这项工作将是第一次这样的应用1/D 扩展到连续统问题。 该方法具有 它的优点是它处理粒子的集体运动 比其他方法更容易。 这是非常重要的 对He的激发态的准确描述。

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.
