多电子原子能级的Sea-boson方法
Energy Levels of Multielectron Atoms using the Sea-boson Method
摘要：
本文用Sea-boson方法研究了均匀费米系统（Jelmann-manned模型）的对立面，即单个多电子原子。这个系统除了具有少量的电子（有限系统）之外，还非常不均匀。这意味着平面波基不适合研究这个系统，相反，我们使用由电子与位于原点（理想原子）的原子核相互作用的本征函数组成的基。我们计算了该体系的能级和极化率，并与其他方法如Hartree-Fock方法和赝势方法的结果进行了比较，后者与实验结果进行了比较。
英文摘要：
In this article, we study an antithesis of the homogeneous Fermi system (jellium model) namely a single multielectron atom using the sea-boson approach. This system in addition to having a small number of electrons(finite system) is also extremely inhomogeneous. This means that the plane-wave basis is ill-suited to study this system, instead we use a basis consisting of the eigenfunctions of an electron interacting with the nucleus situated at the origin (ideal atom). We compute the energy levels of this system and polarizabilities and compare with the results of other approaches such as Hartree-Fock and pseudopotentials for the former and aysmptotic wavefunctions for the latter and with experiments.
