|Abstract:||Dispersion relation, transfer resonant energy, growth rate and marginal stability of the electrostatic ion cyclotron wave in the presence of parallel electric field using the loss-cone distribution have been presented for the auroral acceleration region. It is found that the effect of parallel electric field is to stabilize the wave and enhance the transverse acceleration of ions whereas the effect of steepness of loss-cone distribution is to enhance the growth rate and decrease the transverse acceleration of ions. The results are interpreted for the space plasma parameters appropriate to the auroral acceleration region|
