It is observed that difference in the temperature of electron and positron have a significant effect on the behavior of self-focusing, when the density of electron slightly exceeds density of positron. %> http://opsi.ir/article-1-182-en.pdf %P 373-376 %& 373 %! %9 Research %L A-10-1-162 %+ %G eng %@ 1126-3278 %[ 2014
