Positron-acoustic Waves in an Electron–Positron Plasma with an Electron Beam

Australian Journal of Physics 49(5) 967 - 976
Published: 1996


The nonlinear wave structures of large-amplitude positron-acoustic waves are studied in an electron–positron plasma with an electron beam. We present the region where positron-acoustic waves exist by analysing the structure of the pseudopotential. The region depends sensitively on the positron density, the positron temperature and the electron beam temperature. It is shown that the maximum amplitude of the wave decreases as the positron temperature increases, and the region of positron-acoustic waves spreads as the positron . Temperature increases. The present theory is applicable to analysing hirge-amplitude positron-acoustic waves associated with positrons which may occur in interplanetary space.
