功形式Hartree-Fock近似下的正电子和正电子偶素亲合能
Positron and positronium affinities in the work-formalism Hartree-Fock approximation
摘要：
在Harbola和Sahni为卤素阴离子和Li^-至O^-（不包括Be^-和N^-）体系提出的功理论中，研究了正电子与阴离子的结合。经验地发现正负电子束缚系统的基态总能量是Hartree-Fock能量的一个上限。计算的期望值以及正电子和正电子偶素的亲和力与它们的限制性Hartree-Fock对应物吻合得很好。结合的正电子中性物种也使用迭代方法进行了研究。
英文摘要：
Positron binding to anions is investigated within the work formalism proposed by Harbola and Sahni for the halide anions and the systems Li^- through O^- excluding Be^- and N^-. The toal ground-state energies of the anion-positron bound systems are empirically found to be an upper bound to the Hartree-Fock energies. The computed expectation values as well as positron and positronium affinities are in good agreement with their restricted Hartree-Fock counterparts. Binding of a positron to neutral species is also investigated using an iterative method.
