Klein-Gordon方程、Dirac方程和相对论定态薛定谔方程的比较

Comparison among Klein-Gordon equation, Dirac equation and Relativistic Stationary Schrodinger equation

Guang-jiong Ni, Weimin Zhou, Jun Yan

摘要:

粒子总是不纯的。它总是隐藏着反粒子成分,这是狭义相对论的本质。在此基础上,重新研究了Klein-Gordon(KG)方程和Dirac方程,并与相对论定态薛定谔方程(RSSE)进行了比较.当一个电子被束缚在一个具有电荷数为$Z$的点状核的类氢原子中时,在狄拉克方程中$Z, Z_c$的临界值等于137,而在RSSE中则为$Z_c=\sqrt{M/μ} (137)$,其中$M$和$μ$分别为原子的总质量和电子的折合质量。

英文摘要:

A particle is always not pure. It always contains hiding antiparticle ingredient which is the essence of special relativity. Accordingly, the Klein-Gordon (KG) equation and Dirac equation are restudied and compared with the Relativistic Stationary Schrödinger Equation (RSSE). When an electron is bound in a Hydrogenlike atom with pointlike nucleus having charge number $Z$, the critical value of $Z, Z_c$, equals to 137 in Dirac equation whereas $Z_c=\sqrt{M/μ} (137)$ in RSSE with $M$ and $μ$ being the total mass of atom and the reduced mass of the electron.
