We present results of stereographic measurements of interlayer magnetoresistance in the quasi-two-dimensional (Q2D) organic conductor alpha-(BEDT-TTF)(2)KHg(SCN)(4) at around charge density wave (CDW) transition temperature T-c similar to 8 K. At 2 K in the CDW phase there exists the anomalous Lebed resonance pattern the amplitude of which is modulated by Danner-Chaikin oscillations in case of applied magnetic field close to the Q2D conducting plane On the contrary at 7 K Just below T-c, we have found that the Kajita oscillation of the cylindrical Fermi surfaces appears superposed on the anomalous Lebed resonance A quantum model of interlayer tunneling demonst
