我们证明了在E-Fermi-Dirac-von Weizsäcker理论中,电荷Z > 0的核最多能束缚Z + C个电子,其中C是普适常数.这个结果是通过与托马斯-费米理论的比较得到的,后者作为副产品,给出了屏蔽核势和极小值半径的界限。证明的一个关键因素是一种控制外部区域粒子的新技术,该技术也适用于具有核背景势的液滴模型。© 2017 Wiley Periodicals,Inc.
We prove that in Thomas–Fermi–Dirac–von Weizsäcker theory, a nucleus of charge Z > 0 can bind at most Z + C electrons, where C is a universal constant. This result is obtained through a comparison with Thomas‐Fermi theory which, as a by‐product, gives bounds on the screened nuclear potential and the radius of the minimizer. A key ingredient of the proof is a novel technique to control the particles in the exterior region, which also applies to the liquid drop model with a nuclear background potential.© 2017 Wiley Periodicals, Inc.
