    1. If φa(r1)=φa(r2)φa(r1)=φa(r2)\varphi_a(\mathbf{r}_1) = \varphi_a(\mathbf{r}_2), then |φ−i⟩=0|φ−i⟩=0|\varphi^{−i} \rangle= 0. Thus there is no possible antisymmetric combination involving electrons in the same state (spin-orbit). This is the Pauli exclusion principle.

      Can some one explain in details?
