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.

基本粒子理论中成功使用的维缩放方法应用于原子物理学的问题。 已经在约束状态问题上提出的应用表明，与其他扰动理论一样，该方法具有原子理中定量工具的潜力。 这里预期的申请是涉及HE的双重激发态的问题。这些状态正在自动化，这项工作将是1/D扩展到连续性问题的第一次应用。 该方法的优点是，它比其他方法更容易处理颗粒的集体运动。 这对于对HE激发态的准确描述很重要。
