| Abstract: | The steady motion of a massless electron-positron gas in a self-consistent electromagnetic field is considered. In such a gas, two phases are formed for each of the components: a dynamic phase, in which the particles move with the speed of light, and a static phase, in which the particles move with a subluminal speed. The static phase can exist only within the capture region, in which the conditions (E,H)=0 andE2<H2 are satisfied. Strong and weak discontinuities of the electromagnetic field on the boundary of the capture region (at the phase interface) are studied.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 1, pp. 165–172, January–February, 1990. |
