Ion acoustic waves excited by large amplitude electron plasma wave were found in the VLF wide band spectrograms whose spectra are very similar to those obtained by the K-9M-35 nonlinear wave-wave interaction experiment. In addition to these, banded LHR emissions were observed throughout the experimental period which, at a certain altitude, triggered 'risers' whose spectrum is very similar to that of ASE. After the electron beam with energy lower than 3 eV is ejected, periodic U-shaped discrete emissions were observed. The frequency of these emissions is lower than LHR frequency and decreases as the beam energy is increased. Generation mechanism of the U-shaped discrete emissions cannot be explained by any linear instability due to hpamwavp intprartinn, 資料番号: SA0124426000}, pages = {577--585}, title = {K-9M-41号機による非線形波動-波動及び波動-粒子相互作用ロケット実験}, volume = {10}, year = {1974} }
