Investigations of the transformation of longitudinal oscillations into transverse ones in beam-plasma discharges have just barely begun [1]. We report here a theoretical and experimental investigation of the efficiency of the processes of transformation of longitudinal waves into transverse ones [2, 3] as a function of the direction of the longitudinal density gradient, and it is shown that the sign of the density gradient influences strongly the radiation intensity of the transverse waves.
