• The dispersion relations for the waves propagating in a magnetoactive plasma are obtained from the Boltzmann eqation with a collision term of the electrons. Two cases in which the wave vector parallel and perpendicular to the uniform magnetic field are studied. Under the assumption that the unperturbed distribution is a spherical shell in velocity space in each case, and two dispersion relations to the zeroth approximation in K are obtained as follows: (A) ω(ω+iv)^2=ω_p^2(ω+iv-iV/3 <dv>/<dV>) and (B) ω(ω±ω_c+iv-iV/3 <dv>/<dV> where ω_c and ω_p are the cyclotron and the plasma frequencies respectively, and v is the collision frequency with the neutral particles. After some calculations under an assumption v(v)=const×v^h it is found that initial pertur bations grow exponentially for h>3 in (B) and the growth rate is the largest in the magnetic field-free case.
