N2 - It is experimentally verified that the dominant region of the nonresonant ion-quasimode is 1ω0/ωLH (ω0: pump frequency, ωLH: lower-hybrid frequency), by controlling the linear Landau damping and the collisional damping of the parametric decay waves by varying neutral gas pressure, and this ion-quasimode have the maximum amplitude at the ratio [formula omitted]. The measured frequency, amplitude, and threshold of the low frequency decay wave are in good agreement with the Porkolab's theory of the nonresonant ion-quasimode including the effect of electron-neutral collisions.
