Microscopics of meson degrees of freedom in nucleons and mesons in   nuclei - what can be seen in the process of quasielastic knockout of mesons   by high-energy electrons
  Developed earlier concept of quasielastic knock out of pions from nucleons by high-energy electrons is propounded as a tool for checking microscopical model ($^3P_0$ - fluctuation) for decay of N to different channels $\pi+B$ and Preparata model of nucleus structure.
