Abstract :
Summary form only given, as follows. A gyrobroadening process causing the perpendicular energy of fast ions to be broadened by cyclotron instabilities due to the weak relativistic mass variation of the fast ions in magnetized plasma is reported. At low cyclotron harmonics, a two-gyro-stream instability can be excited with the involvement of thermal ions if the condition l/sub f//spl omega//sub cf/\n\n\t\t
