We analytically solve kinetic equation in the extended Brillouin zone and demonstrate that the interference effects which occur as electrons move along open orbits result in the appearance of Magic Angle (MA) minima of resistivity. A comparison of our theory with MA phenomena observed in resitivity component ρ (H, α), perpendicular to conducting layers in (TMTSF)2X and α -(BEDT-TTF)2MHg(SCN)4 conductors, shows a good qualitative agreement, including the first explanation why MA's with large indexes, N > 1, are observed in (TMTSF)2X (X = ClO4 and PF6) and α-(BEDT-TTF)2MHg(SCN) 4 compounds. Both physical meaning of the above mentioned interference effects and mathematical expressions for ρ (H, α) are different from that in a so-called OsadaÕs model.
