It is planned to study both bound and continuum properties of lightly ionized medium- to high-Z atoms and ions. Both relativity and electron-electron interactions (correlations) must be considered. The case of negative ions is particularly challenging, as most such systems are unbound in the absence of correlations. It is intended to extend present bound state methods to include the continuum case, permitting for example a discussion of photoionization. The present bound state methodolgy will also be extended to permit a treatment of middle of the row transition metals.

计划研究轻度电离的中高Z原子和离子的束缚和连续性质。 相对论和电子-电子相互作用（相关性）都必须考虑。 负离子的情况特别具有挑战性，因为大多数这样的系统在缺乏相关性的情况下是未结合的。 它的目的是扩展目前的束缚态方法，包括连续的情况下，允许例如讨论光电离。 本束缚态方法也将被扩展到允许处理中间的行过渡金属。
