Notes:
A nonlocal theory of parametric decay of an upper-hybrid wave into an ion-acoustic wave and an upper-hybrid sideband reveals that an axially symmetric pump tends to excite axially symmetric modes. The growth rate falls off with the frequency ω0 of the pump and the azimuthal model number l of the decay waves. In cases where ion and electron temperatures are nearly equal the decay process goes over to nonlinear ion Landau damping; however, the behavior of the growth rate with ω0 and l remains the same. The resonant and nonresonant decay via ion-cyclotron modes also show similar behavior, although with a smaller growth rate.
