Abstract
The non- relativistic equntions of motion fo r a chnrged
par t icle , an electron , in a wave of slowly varying amplitude aro
examined . The ',/ilv e , whistle r wave , is supposed to be propagating
at an arbitr ary but small angle to a uniform background magnetic
field , in nn infinite collisionless plasma . Approximate solutions
f or t he equations of motion of particles in cyclotron resonance
with the shistler wave are evaluated by method of ave r aging .
An expr ession for the period of trapped par t icles i n a lIpotential
well" and an integral of motion in the space of phase difference
are der ived .
