赝相对论原子的大Z行为

The large-Z behaviour of pseudo-relativistic atoms

Thomas Østergaard Sørensen

摘要:

本文研究了电子具有相对论动能sqrt(p^2c^2+m^2c^4)-mc^2的原子基态能量的大Z行为。我们证明了在Z中的领导顺序的能量是相同的,在非相对论的情况下,由(非相对论)的Escheras-Fermi理论。为了使问题有意义,我们保持乘积Z*alpha固定(这里alpha是索末菲精细结构常数),并且小于或等于2/pi,这意味着当Z趋于无穷大时,alpha趋于零。

英文摘要:

In this paper we study the large-Z behaviour of the ground state energy of atoms with electrons having relativistic kinetic energy sqrt(p^2c^2+m^2c^4)-mc^2. We prove that to leading order in Z the energy is the same as in the non-relativistic case, given by (non-relativistic) Thomas-Fermi theory. For the problem to make sense, we keep the product Z*alpha fixed (here alpha is Sommerfeld's fine structure constant), and smaller than, or equal to, 2/pi, which means that as Z tends to infinity, alpha tends to zero.
