摘要： On the electronic structures of quantum dots, there is a new viewpoint saying that, in some specific states, a few electrons might behave as valence electrons moving outside surrounding a core. To clarify the validity of this viewpoint, a numerical calculation was performed in this paper. The results are against this viewpoint.
