| 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 |
