Fermions: Dirac Internal Exchange Frequencies

Using real fields instead of complex ones, it was recently claimed, that all fermions are made of pairs of coupled fields (strings) with an internal tension related to mutual attraction forces, related to Planck’s constant. The solution to Dirac equation gives four, real, 2-vectors solutions ${\psi }_1=\left(\begin{array}{c}{U}_1\\ D_1\end{array}\right)$ ${\psi }_2=\left(\begin{array}{c}{U}_2\\ D_2\end{array}\right)$ ${\psi }_3=\left(\begin{array}{c}{U}_3\\ D_3\end{array}\right)$ ${\psi }_4=\left(\begin{array}{c}{U}_4\\ D_4\end{array}\right)$ where (${\psi }_1,{\psi }_4$
