In this work the instability of the transverse modes with left-hand polarization and frequencies around the ion-cyclotron frequency, propagating parallel to an external magnetic field in an unbounded homogeneous electron beam- plasma system, is investigated. The beam velocity is assumed to be parallel to the magnetic field. The ion distribution is assumed to have a certain velocity spread perpendicular to the external magnetic field, as a result of a possible ion-cyclotron resonance interaction with the instability. It is shown that even for very small values of this average perpendicular velocity the instability ceases to exist, practically regardless of the value of the beam velocity.
