  Abstract:
The dispersion relation of the half-cyclotron waves excited by the interaction of the two counterstreaming electron-positron-plasma beams is obtained. Furthermore, obtaining the growth rate and the threshold for the instability development, the excitation of the half-cyclotron waves in a system of two rotating monoenergetic electron-positron counterstreaming beams flowing parallel to the external magnetic field is investigated.
