Vi. Berezhiani et al., THEORY OF STRONG-ELECTROMAGNETIC-WAVE PROPAGATION IN AN ELECTRON-POSITRON-ION PLASMA, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 50(1), 1994, pp. 448-452
The propagation of intense electromagnetic radiation in an admixture o
f unmagnetized electron-positron-ion plasma is investigated analytical
ly. It is shown that relativistically intense electromagnetic radiatio
n in the presence of heavy ions, in contrast to the case of a pure ele
ctron-positron plasma, may be localized with the generation of a humpe
d bipolar potential in the plasma. This potential may cause an acceler
ation of particles in such a plasma.
