Oblique Langmuir solitons and their self-compression in the "free path" regime
Antipov S.V. , Nezlin M.V. , Trubnikov A.S.
Slow (—motionless relative to the plasma) oblique Langmuir solitons with high-frequency (HF) population were observed experimentally for the first time in a magnetic collision-free plasma on the branch of the waves with linear Trayvelpis-Gould dispersion (1). The solitons are produced as a result of the modulation instability (self-compression) of nonliner waves and their evolution in the "free path" regime, i.e., after extinction of the electron "excitation beam,"
