EXCESS NEGATIVE CHARGE OF ELECTRON-PHOTON SHOWER AND THE COHERENT RADIATION ORIGINATING FROM IT. RADIORECORDING OF SHOWERS UNDER THE GROUND AND ON THE MOON

Electron excess in electron-photon showers connected with positron annihilation in flight and with the contribution of compton and delta electrons in the cascade is considered. It is shown that at the maximum of the cascade development this excess appears to equal 10% of the number of the particles in a cascade. The Cerenkov radiation from this moving excess charge of a shower in dense media is estimated. The possibility of recording and using this radio emission of showers produced in blocks of dense matter by high-energy particles from an accelerator or from the cosmos is shown. It is indicated that there exists the possibility of recording the radio emission from the showers of penetrating particles in underground layers in which radio waves can propagate and in the moon ground with equipment brought to the lunar surface.
